Hello, I am a mother of 4months old baby girl and her weight is now 4.9kgs, birth weight was 2.8 kgs, every month her weight increases around 500 to 550 gms, is it normal? I have also one doubt, i notice that my baby vomits everyday just like curd and whenever I suffered from accidity problem, her vomits also increase. is there any relation between my accidity and her breastfeeding? if so, then is it safe to take medicine for accidity on regular basis? please guide me.
