My 14 week DD has started getting really fussy at the breast. She'll drink for a while and then break off so I'll wind her but then when I try and put her back on she gets agitated and screams and cries. I'm sure she hasn't had enough but can't get her to take any more. She's been spitting up a lot more lately and sometimes wakes up screaming. I'm just wondering whether it could be reflux - can it come on suddenly? She's also teething and having a lot of problems with it so wondering if it could be that? We've tried giving her a bottle but she's not a fan. Any ideas welcome as it's really distressing for all of us. Thanks.
