Replying to Jordan Jones33708 The 4mo sleep regression is a milestone many families are familiar with. It can be brutal— especially when your baby had been giving you good stretches of sleep during the night! 😰 Rest assured, things WILL go back to normal once baby’s body has had time to heal (if they’re sick) and they’ve made the big (circadian rhythm) leap. Some tips and tricks to get though the 4mo sleep regression: ✅ Keep baby’s bedtime routine the exact same. Your baby needs consistency now more than ever. Continue including some variant of a bath/water time, a lotion massage, snuggles, books/story time, and one last BIG feed for the night before putting them down. ✅ Avoid using bright lights around the home (or any room the baby is hanging out in) at least an hour before bed. Instead, opt for ambient lighting like candles, tea lights, and/or red light bulbs! Red does not emit ‘blue light’ which is known to hinder melatonin secretion and disturb our body’s circadian rhythm. ✅ Make sure baby isn’t waking up because they’re cold! Dress baby in the appropriate amount of layers to stay warm during the night. A colder house temp requires thicker layers. Opt for natural fiber PJs (wool or cotton) and a thick sleep sack. Consider running a space heater or stand alone heater in the nursery or sleeping area if your home is drafty or runs cold. ✅ Feed babe as much as they want during the day. You want your baby to consume a majority of their calories during waking hours to limit the number of times they’re waking up during the night to eat. Remember, progression and regression go hand in hand! Your got this!
