I'm sure this is normal but gosh it's draining. More than anything I want my boys to be best friends and take care of one another through life but right now they can't even share a plate of cheese and crackers. They are both vocal and independent and maybe that's why they won't give an inch.
I wonder when the bickering stops? Hopefully before my sister and me - I think we were in our teens before we actually liked each other!
