My 3rd baby is 5 months old and so much harder that my first 2. She will only sleep for about 20 minutes at a time and she fights me all the way as she won't self soothe and has to be rocked. She crys when ever I put her down to do anything untill she goes red.At night she will wake 5 to 6 time for what seems no reason as she very often doesnt want her milk. I have to rock her back to sleep or put her In with me which I dont like doings but im so tired I need to sleep. My first 2 were very good at sleeping and at this age would be happy in there chair or on a playmat. Would love to know if this is normal and when it will get better.
