DS is 15wks and very small, born on 9th centile but dropped to below 2nd, currently around 0.4th, he has always been a bit of a fussy feeder but the last few weeks it has got really difficult. He latches on and then tugs as far backwards as he can and tries to feed with a really poor latch and milk dribbling out the side of his mouth, if I try to draw him closer he arches his back and pulls backwards even further, he also squirms around, bites with his gums and often comes off screaming or pulls so far backwards he tugs off and starts screaming. He used to feed for an hour every 2 hours in the daytime but now often just feeds for five or ten mins before seeming to give up but doesn't seem very content. I know his feeding pattern is changing as he gets older but it seems a very drastic change and I worry he is not getting enough, every time he gets weighed by HVs I come away very demoralised feeling like I must be doing something wrong but can't work out what it is.
He has been very windy and I thought a lot of the fussy feeding was due to that as he squirms and farts through the more difficult feeds but have started to wonder if it is me doing something wrong, as he gets bigger I don't seem to be able to get such a good latch, I feed him on a pillow but would really like to be able to feed without one but trying to make changes to his feeding position just really stress him out.
I'm trying not to stress about his weight as he is getting bigger just very slowly, switched to just feeding on demand a couple of weeks ago (used to wake him in the night for feeds and feed every 2 hours dring day as advised by HV) and so he is now feeding a lot less than before, he goes to bed at 8pm and mostly sleeps through till 5/6am and thenseems hungry roughly every 2-2.5 hrs in the day so some days only has 4 feeds in 24 hours and these can be really short feeds. Can this be enough? Sorry this is a bit long & waffly!
