12 Hours by 12 Weeks: A Consultant Reviews the Plan

12 Hours by 12 Weeks is Suzy Giordano’s book Twelve Hours’ Sleep by Twelve Weeks Old, written with Lisa Abidin. It is not Babywise, although the two are often confused. The plan sets four daytime feeds about four hours apart, gradually removes night feeds, and aims for 12 hours of night sleep and about three hours of naps by 12 weeks. The structure suits some healthy, well-gaining babies, often bottle-fed ones. The 12-week target is marketing, and dropping night feeds at that age needs your pediatrician’s sign-off first.

I make my living in this industry, and this book has a loyal following among parents of twins. Here’s what it offers, where it oversells, and who it suits.

Who wrote it, and what it is

The publisher’s page lists the book as by Suzy Giordano with Lisa Abidin, foreword by Michael Abidin, M.D. It was published in January 2006 and runs 176 pages. Giordano is described as a mother of five and “the Baby Coach,” an infant sleep specialist for Washington, DC-area families. Abidin is described as a mother of twins who worked as a law clerk and prosecutor. The book is still in print, and you can find it as Twelve Hours’ Sleep by Twelve Weeks Old.

The publisher’s copy promises a “Limited-Crying Solution” that “will get any baby to sleep for twelve hours at night—and three hours in the day—by the age of twelve weeks old.” It says the plan has been tested on singletons, twins, triplets, babies with special needs and colicky babies “and it has never failed.” Hold onto that sentence. I come back to it below.

Giordano still runs a consulting business. The Babycoach describes its top service as a 30-minute phone consultation, a custom plan, three to five nights of hands-on training, and a two-week support period. It sets out to remove “habits that may impede progress such as; feedings, swaddle use, swings, pacifier use.”

The plan, as it runs

I’m describing the method from the publisher’s copy and from Shortform’s summary of the book, not from memory. Its building blocks:

1. A starting line. The summary lists entry requirements: at least 9 pounds, at least 24 ounces of milk a day, and a minimum age of 4 weeks for a single baby, 8 weeks for twins and 12 weeks for triplets.
2. Four daytime feeds, four hours apart. The summary’s worked example is 7 a.m., 11 a.m., 3 p.m. and 7 p.m., with about 15 minutes of leeway either way.
3. Night feeds removed gradually. Night feeds are tapered rather than stopped overnight. The goal is 12 hours from the evening feed to the morning one.
4. Set naps. About an hour in the morning and two in the afternoon, which is where the “three hours in the day” comes from.
5. The Limited-Crying Solution. When the baby fusses, wait a few minutes (the summary says three to five). Then comfort them in the crib by staying close, stroking their tummy, giving a pacifier or speaking softly. Leave once they’re calm and repeat if needed. You don’t take the baby out of the crib.

What it gets right

Comfort in the crib is a sound middle path. You stay nearby and soothe without lifting the baby out. That gives a parent something to do besides leave or pick up, and the summary says it’s meant to keep crying short. For parents who can’t face graduated check-ins but find full presence too slow, it’s a reasonable option.

It tapers rather than cuts. Reducing night feeds gradually is kinder and more realistic than stopping overnight. I’d always take a gradual approach over a sudden one, for both baby and parent. My night weaning guide sets out the gentler versions in more detail.

It’s built for multiples. The age thresholds go up for twins and triplets, and the publisher highlights that the plan was tested on them. In consults, the pattern I see with twins is that two babies on two different schedules is how parents go under. A shared, fixed timetable is often what saves them, and this book takes that seriously.

It’s specific. You know exactly what to do at 11 a.m. For an exhausted household, being told plainly what to do is a relief in itself.

Where it oversells

“Twelve weeks” is a target, not a stage of development. The AAP’s parent site says that “babies do not have regular sleep cycles until about 4 months of age,” and that “different babies have different sleep needs.” Some babies do settle into long nights by three months. Many healthy babies don’t, and they aren’t failing. A target in the title becomes a test that parents feel they’ve failed.

Four feeds a day is not how most young breastfed babies eat. The AAP’s page on how often babies should eat says breastfed newborns usually nurse about every 2 hours, with 10 to 12 feeds in 24 hours as the norm. It also says most healthy full-term babies should be fed whenever they seem hungry. The 24-ounce entry requirement also assumes you can measure what your baby drinks, which is easy with a bottle and hard at the breast. For a breastfeeding parent, a four-hour plan from one month raises real questions about milk supply. Ask an IBCLC or your pediatrician before you start.

“It has never failed” is not a claim a book can support. No method works for every baby. If you’re told a plan can’t fail, then when it does, you’ll blame yourself, which is the opposite of what a plan is for.

Removing night feeds is a medical decision before it is a sleep one. Whether your baby still needs a night feed depends on weight, growth and feeding. A book can’t see any of that. Your pediatrician can.

Is it the same as Babywise?

No, but they’re cousins. Both are schedule-led and both promise early nights. Babywise is built around Parent-Directed Feeding and the feed-wake-sleep order, and it carries a 1998 AAP warning about parent-scheduled feeding. I’ve covered it separately in my Babywise review. 12 Hours by 12 Weeks is more mechanical: fixed four-hour feeds, a set nap pattern and a comfort-in-the-crib technique. If a summary tells you it’s a Babywise book, the summary is wrong.

The free version of this advice

House rule: every review names the no-cost route first. The parts of this book that hold up are free. Keep daytime feeds full and roughly regular. Keep night feeds calm and dark. Comfort your baby in the crib before you lift them out. Once your pediatrician confirms a night feed is no longer needed, reduce it gradually. Your library probably has a copy if you want the original.

What I’d tell a client

If you’re feeding by bottle, your baby is gaining well, your pediatrician is happy, and you like a structured day, this is a clear and humane plan. The comfort-in-the-crib technique is worth learning whatever method you use. If you’re breastfeeding, or your baby was early, is slow to gain or has reflux, don’t start from the book. Start with your pediatrician, and that’s a pediatrician conversation, full stop. And drop the twelve-week target. Judge the plan on whether nights are getting longer over a few weeks, not on a date in the title.

FAQ: 12 Hours by 12 Weeks

Who wrote 12 Hours by 12 Weeks?

Suzy Giordano, known as the Baby Coach, with Lisa Abidin. The full title is Twelve Hours’ Sleep by Twelve Weeks Old, published in 2006. It is not a Babywise book.

Is 12 Hours by 12 Weeks cry it out?

No. Its Limited-Crying Solution has you wait a few minutes, then soothe your baby in the crib without picking them up, and repeat as needed. Expect some fussing; you are not leaving the baby to cry alone.

Does 12 Hours by 12 Weeks work for breastfed babies?

Some breastfeeding families use it. Four feeds a day is far fewer than the 10 to 12 a day the AAP says is typical for breastfed newborns, so check supply and weight gain with an IBCLC or pediatrician first.

What if my baby isn’t sleeping 12 hours at 12 weeks?

That’s normal. The AAP notes that regular sleep cycles don’t appear until about four months, and sleep needs vary from baby to baby.

Does it work for twins?

It covers them directly. It sets a later starting age for twins and triplets than for single babies, and a shared timetable often helps families with more than one baby.
