yes as a baby he was super friendly and would always sit in my lap. my kids are 4.5 and 2 yrs old.
I'm sorry... in my experience, he HAS to go...
Your kids are too young to risk his behavior going forward. They could easily be blinded at that height. Also I wouldn't want them to become scared of chickens due the behavior of one hormonal idiot.
I was SOOO excited for my first young cockerel that sat on my lap and acted so sweet! Before being removed to the stag pen, he tried to pull a hen off my lap. The first time I felt something brush my leg I didn't realize it was an attack. The second time, I had wised up. It eventually became rushing me at the fence, stalking me and pretending to do busy work if I looked at him. Then crowing AT ME relentlessly. After being attacked every time I turned my back for several months... I'm not gonna lie... The meaner the roo, the sweeter the stew!
Took me a while to get past that. Since then I have had a good rooster... who didn't look cross eyed at my dogs. He did drop his wing to try and dance at me ONE morning. Which I quickly corrected and he was my best rooster yet. He was not a lap cockerel.
Now some people have luck and get good boys even though they were lap boys. That was not my experience and NOW I don't have lap boys and will NEVER recommend it. I teach them to avoid me. Not that I'm a threat per say and also not to be seen as part of the pecking order... More like a master. The giant who brings food is NOT to be challenged, they are accepted as part of the normal routine.
Note... now all stags get separated into the stag pen before they reach mating age... so they can gain some maturity and manners.
I know it's a hard decision... but I can almost guarantee you that you will have a happier family and flock if you rehome him ASAP, but don't advertise him as friendly because it is misnomer and he now has hormones kicking in. You can always add another boy down the road, when you have more experience or your kids are a bit taller. Separation to me is not a good choice since accidents happen and he could get out just to go after one of the kids. And I wouldn't want that sort of liability if I had other children visiting.
Check out post #18 in this thread to see the rooster training I was speaking of. It didn't work for me... but each bird is an individual. I also don't follow much of the whole don't let him eat in front of you thing. At this point his behavior really is a misunderstanding created by you. But don't blame yourself, we all do our best until we learn something new! ...

Now I keep it simple... treat them as chickens. Yes I walk through them and not moving is an indicator of things to come. People think "friendly" chickens are friendly... WRONG, they are in fact confident. I go mostly hands off once identified as cockerel... that is to say, I handle them when I want to, whether they like it or not. But NONE (boys) will be invited to hang out on me... NOT even Silkies! Yes, I've been attacked by Silkies to.
Good luck whatever you decide.
