Ilyas at toddler class

It's been 1 week n 1 day that ilyas joined the toddler class at LV. Teacher senita feedback is that he's adapting well. It's just that she observed ilyas is quite aggressive. On one hand I'm worried that he's picking up the wrong things but on the other hand, I'm glad he's able to do that. A little aggression is gd. Too much will be a diff story.
