Well, start raising the baby - same way you raised Ernst - feed it and play games :furawatchi:
73yrs is pretty old for a Tama to have a baby - normally ppl are bragging about getting their tamas to live that long - and they are usually an Ojitchi or Otokitchi by then ... but 73lbs seems within the normal range - if a little on the heavy side :furawatchi:
Congrats on the new little one. My little Annie is still 0 years old thought I've had her for two days. I had to suspend her a couple of times for abt two hours or so. i'm guessing that did it.
