Are we playing with fire?

It's still crazy to me that we're already pregnant with our last baby.  Such a bittersweet pregnancy; super exciting to be pregnant again as I've missed it, but also it is our last baby so I wont be able to experience pregnancy again...well unless we have an oops or something.  But it has me thinking too.  We have such an amazing family dynamic with the two girls and Ace.  We can "tag team" them if we need to, and each girl has bonded more with a certain parent; Kensi to me and Isabelle to Grant.  We're such a happy family right now, is a new baby going to mess that up?  I like to think it wont, and of course our dynamic is going to change, but I'm still a little worried about it.  Could be because I'm a worry wart anyway, but hey...I wouldn't be me if I didn't worry :)  Our house is so full of love and happiness, and the new baby certainly wont change that either.  In a perfect world, both girls would absolutely love the new baby and nobody would feel left out.  I wont lie, that's exactly what I'm going to shoot for when baby comes.  Making sure that I still have time for each girl and that we play together too.  I never want my children to feel like Mommy doesn't have time for them, or that I love one child more than the others.  I know I'm not Super Mommy, but I'm hoping that I can help keep our dynamic pretty close to how it is now, with everyone being happy and knowing how much Mommy and Daddy love them!
