my son is almost 7 months old and he usually falls asleep on the bottle around 8pm but lately he is still awake when he finishes, he's starting to nod off but when we try and put him in his crib, he gets upset, crying and becomes fully awake, we give him the pacifier to help calm him down but he's still upset that we've put him into his crib. what's the best approach to develop a good long term sleep habit?  we are also having trouble establishing a nap routine.
