Most parents know babies need to wake and eat every few hours during the first weeks of life. They then expect stretches of sleep to get longer and longer, until they can finally “sleep through the night.” But the reality is that most babies go through rough patches or sleep regressions, even in SNOO.

The great thing is that SNOO was designed to improve infant sleep during these rocky times—the App has several settings you can customize to give your baby the comforting he or she needs.

Why Sleep Struggles Happen

When should a baby be able to sleep through the night? Four months? Six months? Actually, this is a trick question. The answer is never! In truth, babies never sleep through the night (and neither do adults).

At night, we cycle up and down—between light and deep sleep—punctuated by 2-4 drowsy wakings. If everything is fine, we dive back into sleep and don’t even remember rousing. But if something is wrong, we may wake up fully. 

Your baby enters light sleep every 1 hour. And, if something has changed since she fell asleep (her nose is stuffy, she’s a little hungry, her gums are sore, she’s hearing noise from the TV or the street) she may pop awake.

Another common struggle is the dreaded 3- (or 4-) month sleep regression. Around this time, babies LOVE to chat, flirt and smile with mom and dad! When they wake up, they may call out for their BBFs to come cuddle or just “hang out.”  It’s like your little social butterfly is saying, “Hey, you with the long hair. Come back and play!”

That’s why families get the most benefit when they use SNOO for 6 months…you don’t want to wean to early. SNOO can help babies quickly recover from these ups and downs and return to solid slumber. Unless your baby is over the 25lb weight limit, there really is no rush to transition to the crib.

How to Adjust SNOO to Lessen Sleep Struggles

Now, here’s the good news: If your baby’s sleep has suddenly dipped , you can use the App and try these tips to get your baby back on track:

  • More milk: If your baby is suddenly hungrier at night, offer more milk during the day. Wake her to eat if she’s napping longer than 2 hours, alternate your breasts every 5-7 minutes during a feed to boost the calories and try a dream feed. (If she doesn’t want to concentrate on her daytime feedings, feed in a room away from distractions with some strong white noise in the background.)
  • Good swaddling: Your baby is stronger now. If her arms wiggle free from the bands, try this swaddling trick.
  • More jiggle/shush: Babies who wake because of a cold or sleep regressions often need a few weeks of rocking/shushing on a higher level. (Think of it like driving around with your baby all night, but safer, easier and less polluting.) Go to Settings > My SNOO > SNOO Starts pick a higher baseline.
  • More jiggle/shush 2: Another way to give more soothing sensations is to “lock SNOO on the purple or green level. This is great for babies who need a bit more oomph, but don’t like when the bed revs up too much. Like your car’s cruise control, locking provides a more robust level of motion all night. When SNOO is running at the motion level in which you’d like it to stay, press and hold the “Play” button for 3-5 seconds until you see the “Pause” symbol appear. Note: SNOO will not respond to your babies cry while "locked" on the selected level.

Babies who do better when SNOO is locked higher (or the baseline is raised) usually need it for a while. After 2-4 weeks, trying the lower level again will let you see if your child’s sleep pattern is back to normal.

Teething, colds and growth spurts happen. Fortunately, SNOO’s customizable womb rhythms can often be like a magic wand turning cranky babies into solid sleepers.

It is important that, in preparation for and during breastfeeding, mothers eat a healthy, balanced diet. Combined breast- and bottle-feeding in the first weeks of life may reduce the supply of a mother's breastmilk and reversing the decision not to breastfeed is difficult. If you do decide to use infant formula, you should follow instructions carefully.
