My Son wants to be a Dog

I don't know if this is normal or not but I'm only assuming it is.

Lately Bradley wants to be just like Tabitha, my dog. He chases her all day. He feeds her all day. He "pets" (which is slapping and grabbing) her when he can. Now to top it off, he pretends to eat like her.

He will grab a piece of food, drop it on the ground, then bend over get on all fours and pick it up with his mouth and giggle while it dangles from his mouth. Hes been doing it for a few days now and this is the only way he ate a few snacks this morning.... its so odd to watch. I wonder if he will do that at his party on Sat. That will be amusing for the family.

I am a little interested in how things will go with the babies on Sat. Evie plays nice, they are never a problem. Nate is a year older than Bradley so I'm assuming there won't be too much issues, we have a lot of toys. Elizabeth will also be there, shes only a week older, but Bradley seems to not like her for some reason. I don't know why, I'm not sure at this age what they could possibly come up with as a reason to not like a baby.

Oh well, we will see how it goes. Hopefully everyone will be able to fit in our little apartment! Good luck people :) haha
