My DS is 17 months old, full of beans and starting to get a bit bored at home, so lately I've been trying out a few 'structured' activities for the first time- storytime at the library, toddler music and swimming lessons, based on what he seems to love doing at home.
Although I expected him to be his usual active-non-stop-toddler self at the above activities, I've noticed quite a big difference in his behaviour compared to the other kids (same age group) and it's got me a bit concerned.
While the other kids seem to mostly participate and focus on what is happening, and try to do what is asked of them, my DS is the fully rambuctious ball of energy who won't sit still for even 5 seconds, throws the instruments away and speed-crawls or toddles off to play with the pram/the door handle/pat the younger babies/check out what all the other parents are doing/try and reach something he shouldn't. I calmly redirect and try to grab his attention- at the music classes I am on the floor with him, singing and doing the activities, playing the instruments that he refuses to touch- I might grab his attention for 5 seconds but then he is off and starts twisting away, yelling if I try to stop him. At swimming he is constantly trying to push my hands off him (trying to be independent), climbing out of the pool, not doing any of the activities and just generally trying to do his own thing and hating me trying to contain him. It's not an issue with not liking water as we go to the pool 2-3 times a week and he is uber confident in the water, goes up and down waterslides himself, we've taught him to climb in and out of the pool etc.
So my question is... should I be concerned? Is this normal? I know I shouldn't compare him to other children but it's a pretty obvious and major difference. Do I keep trying with the structured activities or just wait until he is a bit older? Is there an element of self-selection at these classes where the parents with hurricane toddlers like mine stop going and those with more focused ones continue and I'm therefore comparing him to a select group of unusually well-behaved toddlers??
I will add that I otherwise have zero concerns about his development and he is a very bright and happy little bub. But there is a family history of ADHD and that is lurking in the back of my mind...
