DS is just over 12mths, and has been drinking cow's milk for about 2 weeks now. He's become very agitated at night, screaming, clawing his nappy area, twisting in my lap etc. This isn't like him at all. It's worse at night, but he's also become a bit less himself in the day too now, and we're all miserable (and tired!)
He previously drank formula which had cow's milk derivitives in it, and he eats yogurts and cheese ...as i wrote that he also just puked up some milk of the floor and it stinks.
Does any of this sound like it could be cow's milk doing it, or am i just overthinking it?
