Girls, can I drip Kandid drops and smear Kamistad ointment to make it go faster or will I just make it worse for her? She's not eating at all constantly crying when I try to feed her, even not warm but slightly cool mixture ? I don't know what to do so she eats again, wants to eat but when it gets into her mouth she straight up tenses up, she's already weak and became very weak?? Or recommend if anyone had this, how did you feed your babies, because that advice from the pediatrician is useless, just shove and try to feed her, she might choke because she cries??
