I have a 5 year old son with ADHD too. He also acts like a baby, but in a different way. He cries a lot. The other day, he spilled a drink and lost it for 30 min. So annoying!!
I worry that he'll be eaten alive in grade school if he doesn't toughen up.
Here are a few suggestions that have worked for me, although I'm still working on it.
I love Rosemond too. I'm not particularly religious, so I just skip the biblical parenting parts and focus on the fundamentals.
- Before he goes to bed, ask him what he needs -- water, stuffed animals, etc. and explain to him that he won't get anything else. When he complains, whines, etc., explain that it's time for bed and let him cry it out. I don't know how bad it gets, but you might want to try taking all toys, other fun things out of his room.
- About the baby talk. You could try telling him that you don't understand baby talk and ignore him until he talks like a big boy. ...or, when he starts talking/whining, turn your back, walk out of the room and do something else. But give him lots of positive attention when he talks like a big boy.
- Sitting on your lap. If he's constantly hanging on you, feel free to tell him that you need some time to yourself and tell him to sit somewhere else. I know the feeling. My son will hang on me constantly sometimes and I need to tell him to go away. It's MY body and I get to say how much is too much.
- Andrew has been taking Focalin to control his ADHD and it has helped a lot. Every child is different and it's and individual decision for each parent, but we've had great results.
