We are 24 weeks today - a wonderful birthday present for me. The day started out with Jason walking into our room singing "Happy Birthday" to me with breakfast in bed (french toast, my favorite, and a sliced banana... so good!). He's such a great husband.
Now that the babies are 24 weeks, they are just over a pound (up to a pound and a half) and 8-12 inches long (about the size of an ear of corn). They should be able to hear any loud sounds, though they will sound muffled for them because of all the fluid. They don't have much fat on them, but hopefully they will fill out in the next few months.
My belly button is getting more shallow by the week. It's still there (and still indented instead of "outdented"), but I would love to hear your bets on when you think it's going to pop. =)
