It definitely hasn't sunk in yet and I'm not getting too (two?) excited or freaked out. I have two coworkers had twin IVF babies initially but ended up with only one outside baby so I'm just waiting to see what happens over time.
IiiiIIiiii knew it! So glad for happy little heartbeats, and I'm glad life gives you plenty of time to wrap your brain around having two of 'em!
I know, you called it. I think I would have been more surprised to just see one sac than I was to see 2. I was surprised to see heartbeats already though.
