Every week we stay over at my parents' place for three nights and for some reason my one-year-old son's food and milk intake drops to 1/3 of his usual. We use the same bottles, same milk powder, same food prep, same schedule in the day but for some reason, he refuses to eat nor drink. We thought of so many possibilities but can't get around one issue. He is a dream feeder and even when he is sleeping he refuses to drink. However, the moment we go back home he chugs down his milk and eats as he has been in starvation.
He loves to eat and drinks a decent amount otherwise, we just can't figure this one out. It's been two months now, can anyone can help?
