I think it's strange that Bristol is always holding the baby instead of Dad holding the baby. Palin says they broke the news of Bristols pregnancy to quell rumors that Bristol is the baby's mother. They say Bristol is 5 months pregnant but that doesn't mean she isn't Trig's Mother.
She may be 4 months pregnant. Who's counting, right??? I hope her child is born early enough to totally discount the suspicion that Trig is her baby..not Sarah's. If the baby is Bristols child, then the coverup would be shocking, all things considered.
