Tell me what vitamin D you give? We were prescribed water-based Aquap D3. I noticed that the child is sleeping poorly, too excited, and read reviews many complain about it. Tried for two days not to give, slept normally. Today gave again, in the end, he slept only 2 hours and now it's already 11 pm, and he doesn't sleep. Could anyone else give vitamins, recommend something.
