My youngest had very bad colic the first few months so I kept him in our bedroom for the nights. I'm thinking of moving him to his bedroom now but he shares with his sister who is turning 2 in a few weeks. He still wakes up twice a night for a bottle. His sister sleeps well. My worry is that she will also wake up when he does from the noise and she will want to cuddle when I'm.trying to feed him and put him to sleep again. We usually sit with her until she falls asleep. Will it be a disaster? Any tips? Maybe we should wait until they are a little older?
