My 10 week old daughter has never been a great feeder. Due to showing signs and not gaining weight the gp thinks possible CMPA and she's now been on aptamil pepti 1 for a week. All was going well, she was feeding properly, sleeping better, more settled, less crying. That was until 2 days ago. Yesterday she only took 10oz of milk. Usual bath and bottle at 8pm. Since then, so in the last 24hrs, she has only drank 7oz of milk. The doctor wanted to see her immediately as she has been very sleepy. Of course she gets active once we got there at 4.30pm. He's not really that bothered that's she's not feeding as she's active and smiling so sent us on our way. The more I think about it the more annoyed I am, with myself mostly as I should have pushed harder. I just don't know what to do next! Any advice?
