Mommies, my daughter is 2 mo old and BF. Shes not eating like she normally does and she's crying, fussy, and fighting me when I try to feed her. At her 2 mo appt doctor agreed she's already teething. Could that be why she won't eat or even comfort feed? Cause this isn't like her at all. She never turns down the boob and usually isn't fussy like this. My guess is teething but I'm not really sure...
