Hello everyone) I wanted to ask for advice. I need to leave for a week for work urgently, there are no conditions for the child. The baby is 7 months old on GIV, I don't want to wean him, and you can't take him with you. If I will be pumping milk during the week and start feeding him when I get back, will he refuse? Has anyone had such cases? I would like to pump milk as much as possible and freeze it. + He eats porridge and puree.
