Chloe is nearly 15 weeks and the last 5 days she has been really fussy with her bottle and not drinking as much. She was having around 800ml a day now it's a struggle to get 700. Sometimes she will have 200 and sometimes it's hard to get her to have 80. We feed her every 4 hours during the day and she sleeps from 1030pm-6am. It's worrying me that's she is not getting enough and I've just been in tears as she was so fussy with this bottle! Other than that she seems normal. Smiling and having wet nappies. Any suggestions for a worried stressed first time mum.
