Raising a healthy sleeper starts with a consistent bedtime routine. You can start enforcing this when your baby is roughly six weeks old. At the same time every night, read a book together, sing songs, and feed your baby before putting him or her into the crib. It may also help to get your child up at the same time every morning and put him down for naps at regular times.
Do your research! There is a lot of information about there about sleep training, and much of it is controversial or contradicting. However, just like making any important decision, your choice to sleep train (or not sleep train) should be informed by your own reading, research, and inferences. Furthermore, there are many different methods of sleep training (which we’ll cover in this article as well) and you’ll need to decide which method is right for you.
Finding the ideal bedtime can be tricky in the first few months of life. Infants who take a late afternoon nap (say, 4 to 6 p.m.) may go to bed as late as 9 or 10 p.m. A good rule of thumb is that your baby will probably sleep three to four hours after his last nap ends, but you may need to experiment, adjusting your baby’s nap and bedtime schedule to figure out what works best.
"My 5-month-old was waking every two hours at night. I was so tired I wanted to die. I finally caved in, put in earplugs, and let him cry it out – which he did, all night! But then, something amazing happened the next night: He slept a full 12 hours and awoke rosy and cheerful. It's been that way ever since, and he's even a better napper now. I know that it is hard to listen to your precious little one cry, but a sleep-deprived, miserable mom and baby is a terrible thing too."
For my wife and me, those early days passed in a blur. Nights seemed endless, and no government ordinance was about to come along to shorten our shifts. When he was around 3 months old, our son started sleeping for longer periods and our relief was profound. But after about a month, the baby started waking up at night again. After one nightly waking became two, then three and four, I realized it was time to sleep train our son.
If your baby is older than six months, don’t worry, McGinn says: “It’s never too late to develop good sleep habits.” Dickinson says he finds nine months to be a bit of a sweet spot for parents in terms of getting babies to sleep through the night. “They are at a good age for understanding routines and don’t need to eat during the night,” he explains.
