Hi mommies! I just want to ask and advice from you po if what did you do when your LO doesn't want to eat? My LO has no appetite and I'm so sad. I'm a little bit stressed. All she want is breastfeding. She's now 1year and 9month old. Please give me advice. #1stimemom #firstbaby #advicepls #pleasehelp #baby
