Real question for mom’s with children who have ADHD..”*No Judgement Please*

My son is going to be three July 24th, after he turned two this passed summer I noticed an EXTREME advance in how hyper active he is all day long, he wakes up multiple times a night even after doctor recommended melatonin and we tried that for a while. He does not ever have a chill period, and I know that is normal with toddlers particularly, but he does not stop no matter what time of day or night it is. It’s very hard for me to keep up with him being 6 months pregnant after working 9hrs a day, and he even goes to daycare. I’m not sure what else to do, and the doctors will not test him this early. I need some advice..l
