Hi girls, I'm having trouble with Nutrilac, it's not digested, I changed the formula, she often wakes up, doesn't want to sleep even at 12 hours. We're 4 months old and we're on SVs? Has anyone had this happen? And when you give Nutrilac in the box, does it come out on her face? Is there any reaction to Nestomil? She only drinks around 120ml, then she wants more, but she doesn't want to drink anymore. It seems like she doesn't want the formula.
