Well i don't know if this is normal or she is trying to tell me something but up until last week my little girl who is 4 months has been having 7oz at 7am, 11am, 3pm and 7pm then goes to bed around 8 as she is usually falling asleep. She always drank her bottle within half hour. Now she won't go to sleep until about 10pm if not later she's just not tired at all and she won't drink her bottle she will drink about 3oz then doesn't want any more even in the mornings when shes gone about 10hours without one she'l still only drink about 3oz then stop and usually about an hour later she will drink the rest but not always. So i'm just wondering if it's a phase she is going through or whether there is something i am doing wrong??
