My little one done the same, we’ve found giving her a bottle a few times week helps and we changed to lansinoh teats which made a big difference. Sometimes she still refuses but we keep offering her it and she’s getting a bit better xxx
Perhaps the nipple is too big? You can also try offering a cup or syringe
He took a bottle tonight for my mum after refusing for us this morning!
My baby wont let me cuddle and rock her to sleep but dad and gramma can. They do things for others but not us sometimes.
Have you smelt / tasted it? It may be a lipase issue where it makes expressed milk taste funny / soapy. Both mine didn’t take expressed due to this and it’s dead common! Can be higher when it’s been frozen etc
