LO is 3 months old and loves to "stand" on our laps and "jump" and kick. He loves to grab for our hands, my hair, some toys, etc. and he LOVES to be upright to see what's going on. He has excellent head control but isn't sitting up or rolling (lol I'd be amazed if he were!)

I was thinking about getting an exersaucer or jumperoo but he seems too young. I was just curious when you introduced something like that.
