Hi my daughter turned 1 3 weeks ago, so I put her on aptamil 3 as advised. These have been the worst 3 weeks sleep since she was newborn. She usually goes 12 hours without waking, and I don't know if it's the change in milk (I'm thinking it's weaker maybe than the aptamil 2) but it's a coincidence. I should also add that she is eating solids, but she prefers a bottle when she wakes and when she's going to bed. I'm thinking it's not filling her. Someone help as I could be cast as the walking dead this morning.
