My son is actively lying waiting for me to feed him, I only start feeding him, he freaks out, screams even though he doesn't take the sippy cup, just gets crazy right away, although we were peacefully sitting and talking with him before, I only rock him when he's half-asleep and feeds him then, only like that does he eat, he stopped sleeping because of this, I also have to rock him while he sleeps, is it a false refusal? And why? I didn't offend him, although I ran off for a session for a day, maybe he got upset... He cries with me for a couple of minutes, can you tell me what to do ?
