3 month old slow weight gain anxiety

[Kidspetsandcakes]

Hi all, this is my first post and I'm not certain it's in the right place so please bear with me..

I took my 12 week old to be weighed yesterday and in 3 weeks she has only put on 8 ounces and so has dropped almost a whole costume (and she was only daddy to begin with). I am bf on demand and have been since birth. HV advised me to top dd up with expressed milk after feeds, which I have been trying but she doesn't want to take it... she will have a few sucks then spit the teat out... she has also recently started the play about at the end of bf - unlatching and relatching, pulling back and stretching the nipple, waving head from side to side or turning away and smiling, etc. I just don't think she's hungry... I'm at a bit of a loss with what to try now... anyone got any tips?

If it is relevant, she is my 3rd child, she sleeps what I consider a normal amount for her age, is generally alert and happy and has plenty of wet/ dirty nappies...

Sorry for the essay..

HVs can be so funny about this. We had all sorts of fun because DD decided to follow her own line, dropped three centile lines, and then decided to spontaneously start gaining consistently just before we started weaning. We had referrals to the local infant feeding coordinator (HV who's also a lactation consultant), and a paediatrician (although typically the first appointment was after we started weaning, so they agreed to just see her again in a few months, and by then she'd settled onto the 9th centile, where she still is at 18 months).

What sort of colour are her dirty nappies, and have you been observed through a full feed?

It was also suggested that any top ups were given via a supplemental nursing system (sns), basically a tube that you tape to your breast with the other end in the expressed milk so that baby is getting the top up whilst on the breast. We also tried breast compressions and expressing off some milk before latching baby on.

Hi ToniWol, her nappies are normally yellowy brown if dirty. Both LC and HV have observed through a feed and both agreed with me she didn't seem hungry after (had both sides then refused any further feed from either breast or bottle). Seems like most kids just follow their own growth schedule..
