Rosie was in her pram in the seating area where the friends and family would of been if Ralph hadn't driven off anyone who might remotely be happy enough to attend the wedding (and they hadn't rushed to have it in a cheap vegas chapel) - in the big pics dump you can see she was just there hanging out in the pram while Ralph and Pantsu got all their wedding pics and posed with Elvis, they did include her some of these at least. Ralph and Pantsu are still awful people - but I'll give em that they did at least include the baby in a way.
@MirnaMinkoff - In regards to Christmas - I imagine Pantsu might justify it as Rosie won't remember it anyway - so why not go to a cheap mexican diner for Christmas day? I'm sure lots of new moms have scuffed first Christmases - but the difference is those moms at least try to make it memorable for them as a family, even if baby needs pics and video to remember it as well.
But yeah no way Ralph would be left alone with that kid - Rosies use for him is to be a cute baby in pics so he can prove he's at least spawned and he actually gets to be in the same physical space as this baby vs "the other one" - sadly I don't think Ralph will buy into the idea that babysitting or being an actual dad to Rosie will totally own the alowgs unless he does it like once for the novelty of live tweeting it and crowing about what an awesome dad he is.
