Well that's odd. So this child wasn't out in public then (IMHO). No grocery stores, no gas stations, no road cameras ever saw baby A with the mother? No neighbors, no extended family? How incredibly odd.
3 year olds tend to want to play and go places - not sit in the house all day. I know she wasn't feeling well, but what about the days prior?
LL is 8/9 months pregnant in a home with 5 other kids, and not a single person ever came over to help, deliver food, or visit? Where is grammy in all of this?
Did anyone see baby A alive for her birthday? How long has she been "gone"? Come to think of it, I thought it odd that grammy mentioned Christmas and how baby A opened her presents. Erm....Christmas was last year! Doesn't she have any recent visits she can talk about?
This case just gets weirder by the day --
