My daughter has started dropping her feeds to 5 minutes in length. no matter what i do she won't feed any longer. if i try to feed her she refuses ands cries. she is five months. i'm not sure she is getting enough. she feeds every three hours. i tried to extend out the time to 3hrs and 15mins and so on, but that didn't make any difference so i just reverted back to the 3hr mark. as a result she is waking constantly throughout the night and feeding for five mins and sometimes less. can you give me any advice. is she getting enough food. should i feed her everytime she wakes at night as i do and i worry maybe she will always depend on me to put her back to sleep if she wakes.
