4 weeks--Is the newness wearing off?

I really was pleased with how Helen adjusted to Patrick. Its been 4 weeks since he was born (wow!). We've had no major incidents. Helen had a hard time adjusting the first few weeks because I wasn't able to pick her up (thanks to c-section number 2). But other than that, the worst we've had is how much she wants to cuddle him. She likes to lay on him, pet his head, she always wants him "out." Out of his swing, his carrier, etc. She was never bothered when I nursed him. In fact, I think she was starting to like him.

Until today...

This morning I was holding Patrick and she forcefully said "baby! swing!" I got the distinct impression I was not supposed to hold him anymore and needed to dump him in the swing. A few minutes later I heard "baby! bye-bye!" Hmmm...is she ready to send him back? And then the clincher. I look over and her leg is poised precariously above his leg and wham! She steps on him and yells "stomp!" Thank goodness Patrick was 1) fine and 2) pretty laid back about the whole thing. Maybe 4 weeks was Helen's max for a brother.
