Has anyone's 7 month old been not really into rolling. My son has only rolled a handful of times both ways. He still struggles to roll back to stomach he has done it through. I try to give him floor time every day but some days we get really busy so I forget and we have 2 big dogs and a 3 year old so it's hard to just let him play on the floor. He sits up on his own really well also so I usually just sit him up but I'm just wondering if I should be worried?
