For the past week or so my ds has began getting fussy after about 10 mins on the breast. He constantly de-latches/ tries to relatch himself and will cry/scream if I take him away. Even if I put him on the other side he will still cry as if he's still hungry. He doesn't really need burped but does cry/strain when passing (very smelly) gas. No constipation. He arches his body making it really difficult to confort/ hold him. He does sleep about 7 hours every night with a rare feed in between but he's always been a good sleeper. Any tips?
