husband on business trip

My dear husband is on a business trip for 2 days and I really miss him. The kids are keeping me busy and driving me a bit nuts at times. Liam especially seems to be on the tantrum rampage today. Anything I say no to results in a monumental tantrum that gets out of control fast. I don't give in to him, but man I HATE the screaming, crying, kicking that is going on today. I'm trying to be a little understanding since he seems to be missing Ben as much as I am, but at the same time I just want him to be a perfect little angel for me. I guess I must just be asking too much today of both myself and my sweet boys.
