Any advice with getting a almost 5 month old to sleep longer than 2-3 hours a night? I'm so wore out. He was doing good and would sleep 5 hour stretches, which was great, but for the last 3 weeks he gets up every 2-3 hours to eat. He eats 4 oz of formula. I've tried uping it to 5 oz and he gets sick. We have a bedtime routine bath, lotion, warm bottle, no noise and lights off. Nothing works. I've tried all the advice my doctor says, books, and this kid just does not sleep. legit I only get about 4 hours a day total. Nap when the baby sleeps doesn't work because he doesn't nap but 15 minute stretches during the day and it takes me like an hour to fall asleep after laying down.
