your son has low muscle tone. He has no strength to support himself.

Does he always like to sit on the sofa. Does he like to jump, run, or climb or any activity? How's his gross motor? I bet it's hard to ask him to do slides.

My son had same cases as your son before. Now he's much more strong in his muscle. and he's more active now.
