I have 5 month old twin boys that don't sleep longer than 2 hours at a time. They've always been like this. They were pretty good sizes when they were born (6lbs 6oz and 6lbs 2oz) and needed no time in the NICU. Everyone has told me that they'll slowly start to sleep for longer stretches but when will this happen? I'm losing my mind! I'm so envious of mum's who have babies that sleep for 4 hours straight or even have babies that sleep through the night.
