Thats a very young age for playing with puppies.
You have your hands full.
I would suggest that the kids only play with him when you are with them on the floor with him and the kids laying down. So he can take turns playing with the kids, they are too young to play with him without extremely close supervision.
He is a toy dog but not a toy for the kids to play with. My kids were young 5 and up when we got our first small dog and we did the lay on the floor with the pup and the kids and they all learned together how to interact properly with each other. If the pup is played with too tuff and rowdy he will become much more rowdy and aggressive in his play.
Pups can get seriously injured from children carrying them or playing too rough with them, even innocent play can be deadly. Please be very careful with this situation.

Best of luck
