My own son is like that too!

He isn't the oldest of my group but he IS the biggest and he knows it. He has been snatching toys, walking right up and taking the toys away and biting... Sigh.

What I am doing is spending as much one on one time with him that I can. Having him sit on my lap during storytime, I also put him down for nap LAST and wake him up FIRST so we have a good 15 mins of snuggle one on one time without the others.

It will pass I promise you. I am the mom of soon to be 5 and this is SO common at this age whether or NOT you have a home daycare or not.
