WOW! You've got so much on your plate. Alizah is a lucky little girl to have been blessed with you as her mom. And her new cousin is blessed as well. Alizah will go through an adjustment period- she may regress and act more like a baby for a while after the new baby comes home. Giving her a new baby of her own, with some of the items a new baby comes with, can give her a sense of being involved. You could give this to her now, and talk to her about how she has a new baby, and there's another new baby coming, too. Bring her to the hospital or show her pics of the baby, and talk a lot about where the baby will sleep, play, etc. Alizah won't be able to tell you yet, but she can understand a huge amount of what you're saying. Steer clear of saying "Mommy's getting a new baby"- this implies that she's being replaced. Tell her what she is gaining- a new sister, cousin, or however you choose to approach it. And she will be fine. Of course you would worry about it- it's just been you and her together. You may actually go through a mourning process yourself- mourning the loss of that exclusive relationship. But you will be adding another rich dimension to your family, and it will be beautiful in the end. Kudos to you for helping your sister out in her time of need, and for being sure these babies get the love and care they need.
