My sister is having her first baby. My kids are so excited! I have noticed that children from large families just LOVE babies.
My youngest - now 5 - said the day he found out about the expectation of his little cousin, "Mommy, you have to give me LOTS of cleaning jobs, because I need to make lots of money!" I asked what he needed the money for. "To buy the new baby a crib!"
Which I thought was totally adorable. He was already thinking of what the baby needed - and willing to be responsible for making sure the baby had it!
I just love my kids!
