4 month old not eating

She was taking feeds around every 3-4 hours. I've tried to offer her little and often feeds, but with no luck! I forgot to mention she is also fully formula fed since just over two months of age and has been kept on the same brand (Novolac AC). Her usual routine (for the past few months at least) when she wakes up is feed, play/activity and sleep. Last night she slept the whole night without waking but then only had 120mls when she woke up. She is still only small, but now weighs 6kgs. But she has more than double her birth weight. She just woke up from her nap and took 20mls and won't take more. So will offer it to her again soon. She doesn't seem to get hungry anymore. I guess I will keep offering it to her and see if she will take it. She is not showing any hunger cues either. After reading the threads about the four month sleep regression and the dummy (DD has one but only uses it when I first put her down in her cot) it has been very interesting and helpful! She is generally pretty good when she goes down to sleep but if she does wake up during the night, I won't give her back the dummy. She is also learning to go to sleep without it as when she spits it out, I will leave it (but the afternoon nap is the most difficult to get her to settle so sometimes I revert back. I must stop that soon!!). She is normally sucking on her hands anyway! If she wakes during the night, which is not often (touch wood, but have probably just jinxed myself now!), I will let her be and have her talk away. She doesn't normally wake and cry at night so that's why I thoought that she must have been hungry (after checking if there could be other factors). I'm thinking to whether or not to start getting rid of the dummy now. Thanks for your replies and help Edited to add: She was a bit grizzly while rolling over (she sometimes gets one arm stuck!) so offered her bottle again and she took 80ml. So I think I will have to keep offering it to her and see if she will take it. <em>edited by suznz on 10/10/2011</em>

My 4 month old DD has started to be really fussy this past week with her eating. She went from drinking approx 150-160mls to 70mls or 100mls, if I'm lucky, 5 times a day. The morning feeds are generally good where she will have 160mls but things just get worse from there throughout the day. I'm not sure what to do or when to start really worrying. She still has wet diapers, however in the afternoon it starts to become slightly less (as expected as her intake is less) And I don't think she has lost weight. She usually sleeps through from 8pm to 6.30am but this past week has been waking at 3 or 4 for a feed as she isn't getting enough before bedtime. She amazed me two days ago, when she was drinking 160-180mls at every feed (she even had 6 feeds that day!) and I was thinking that things were good again! Haha... she lured me into a false sense of security that she was going to eat!! I don't want to force it as I don't want her to get a phobia of the bottle/food (if it's possible at this age?) but am starting to get concerned. She's also just had her vaccinations at the beginning of the month. Has anyone else experienced this at this age? Should I take her to the dr or wait it out? My main concern is about her becoming dehydrated... Your help is much appreciated as now I'm starting to worry! Edited to say: She is a very happy baby and reaching her milestones (it was actually today that she rolled from back to tummy and vice versa on both sides and won't stop!) I'm a very proud mummy! <em>edited by suznz on 09/10/2011</em>
