Girls, hello!) My son is 4 months old, we're on the go. Everything was great, but now he refuses to take food in the "cradle" position, that is, on his hands. When you hold him up, he starts to fuss and turn around. We never had this before. Lying down eats normally. Has anyone experienced this? What do you think could be the reason?
