Sleeping Situation

Yeah so we got Ethan a toddler bed when we knew the babies were coming so we could get him to start sleeping on his own. He was doing ok, he would go to sleep in his bed sometimes, most of the time he would fall asleep with us and we would put him in his bed, then durring the night ( usually around 2 AM he would stumble into bed with us. Lately he has just been sleeping with us from the get go. He is really stubborn when it comes to sleeping on his own. When the babies came they were really good at sleeping on their own but now they get really fussy when they are put in their crib. So now this is our sleeping situation.........
