Dd2 has been pretty much exclusively breast fed (apart from a couple of times when granny's looked after her) up to now. She's a blw-baby but has still been having lots of breastfeeds ... until yesterday. She has completely refused the breast since about 10am yesterday. When I've tried to 'force' her and got a nipple near her mouth she goes to nip me. So I've expressed and she's had some ebm from a cup, and some hipp follow on milk from a cup so I don't think she'll be dehydrated today. But I find this weird ! Has this happened to your baby ? I've never heard of this happening with a baby under 1. Should I keep expressing or keep trying to b/f or accept she's had enough and just offer formula ? Is it possible she's 'forgotten' how to latch on because she's teething and just has an urge to bite anything in her mouth ? If anybody has any suggestions or this has happened to you, I would love to hear from you !
