My twins are four months old today. I think we are a few days into the four month sleep regression - increased night wakings, nursing at each waking, and taking longer to go back to sleep. Last night my boy was wide awake after nursing at 3 am when nursing usually puts him to sleep. After 30-45 min of rocking and bouncing on an exercise ball I finally put him in the swing where he was nice and calm and eventually fell asleep. I feel they are ready for sleep training but they have their 4 month well visit next Thursday. Should I wait to start until next Friday or start this weekend? What would you do? I go back to work in 2.5 weeks so I'm hoping they start sleeping better again by then. Also can any moms of twins weigh in on sleep training twins?
