Our 3 month old breastfed baby can sleep for 3-5 hours overnight. The problem is nap-time.
He always wakes up like a clock after only 40-50 minutes if sleep. Is there anyway to get him to sleep for longer stretches of time, ideally up to 90 minutes?
His two older brothers were able to do so when they were his age, but I know each baby is different.
Thank you for any insight!
