I need yalls help and opinions. My daugher is 5months and the 1st month we only latched but then the 2nds month I had to start pumping and we still latched but rarely cause I work and go to school and I've always latched and pumped and some days she does fine but lately she keep crying when I off her the boob :( then she crys and I get mad ugh... I think she may have tongue tie or what ever but I'd lm not for sure cause she's had trouble latching since birth but she can latch without a shield now kinda but then she lets go after sucking for a sec.. Any ways to help her latch better or to help cope with getting her back to just the boob
