After 3 1/2 years, my baby is back... (LONG)

You know, you'll be shocked if they stay, how fast they can become yours, and start to fit in. That's not say that maybe they shouldn't go home, but I wouldn't assume that they will never be your little boys again - I've seen that happen with ours very quickly. Sometimes it helps to just focus on the day to day, and give them what you can. I hope it works out!
