My baby falls asleep when feeding and she keeps sucking for atleast 30 mins, but she feeds well (I say this because she wets a whole cloth nappy every 1 to 1 1/2 hours). But when I put her in the crib or bed, she doesn't sleep, she wants to sleep in my arms. Is it normal? How can I make her feed faster and sleep well in crib or bed? since she sleeps when feeding, doesn't sleep for a longer time on the crib or bed ...
