how do you keep one from waking the other up? Ds1 has been sleeping in his crib for a couple of weeks now at least starting off the night but he shares the room with my 2.5 year old who goes to bed about a 1/2 hour later and most nights he ends up waking up his brother getting into bed and winding down. Idk if I should just keep him in my room or what but its getting to be a pain because I end up bringing the baby into my room and putting him in my bed.
