what age did your babies wanna stop being rocked to sleep and did any of your babies self wean and at what age mine has been more interested in baby food or sharing our grown up food lately even when I rock her to sleep she will only suck until she is asleep when before she'd even suck in her sleep she's only 6 months old and my mil (babysits) won't feed her baby food or share much with her (which I'm not too worried about sharing just yet) but seems like baby girl hasn't been eating as much as before (when im gone) and I'm curious if I should worry if she's eating enough. also considering feeding her baby food when I bring her home from nana's (around midnight nights I work) and seeing if that will help her sleep thru the night better.
