The doctor says that it's because The Gravy Baby's immune system was formed in Malaysia, and so it could take him awhile (up to a year!) to get used to the germs here.
And because we've been gone for two years, it could take the hubby and me awhile to build back our immunities, too.
In the meantime, we've discovered some neat apps to entertain us at home.
The Gravy Baby knows how to say "cheese" now.
I guess that's our silver lining.
