Where's baby Abby?

So, for those who don't already know, Tami's sister Marinda had a baby last week. However, baby Abby had some respiratory problems and is still in the hospital. This has been confusing especially to Isaac who went to the hospital with Tami to see baby Abby last week. Tami was able to see her, but not Isaac or Brooklyn yet. Isaac was confused because he wasn't able to physically see Abby and knows that baby Abby is no longer in Marinda's tummy. So he asked, "Is baby Abby in Mike's tummy now?" (Mike is Marinda's husband). At least he's a curious little boy!
