DD is 11 weeks and I noticed a week or so ago that her nappies weren’t as wet as normal even though she seemed to be feeding the same. I got her weighed and she hadn’t gained much weight at all in 2 weeks, only 20g. She then started to fuss and barley latch on, which I presume was frustration.
I started supplementing with formula once on a morning and same on an evening as I was worried about her weight, but made sure to pump each side to maintain what supply I have. She’s now started to barley latch on at all and my breasts just seem so soft and ‘empty’, so she isn’t interested. When I squeeze them milk does squirt out so I’m unsure what the problem is.
Today she’s refused to latch at all and I’ve barley pumped any milk to give her, so I’m gonna have to give her another bottle of formula this afternoon 
Could it be she’s used to a bottle now? I’m so upset and really don’t want to stop BF.
I’d appreciate if anyone had any advice
