My DS is 3 months old today. He rolled over for the first time yesterday! He also hates tummy time......but we do it a few times a day. Yesterday during tummy time he was complaining as usual...then out of nowhere he rolled right over. My poor husband had just walked in the door from work, and missed it my 20 sec. But DS did it later on for him to see!!
I ordered the Bumbo seat...still waiting for it to arrive...but I know DS will love it, as he loves sitting up. I didn't think he would ever roll over (although I knew he was capable of doing it)
Now tummy time is out of the question for us....he just rolls right over...lol
Your ds may as well skip rolling over....no big deal.....and just start to sit. I can't wait for DS to sit on his own! All these upcoming milestones are so exciting!!
