There should be a way to start over with a new baby once you've reached all the achievements. I've uninstalled Little Girl Magic and Orange Tree for the same reason. I love these apps, and when I've bought all there is to buy with the Baby Adoptor apps, I don't want to have to uninstall those too. It's just pointless to keep playing the game and racking up points with nothing to do with those points.
Thanks for your suggestion.
Do you have a Baby Adopter Holidays game, there are other babies.
In any case:
Please check this post how to start over on the iPhone:
Please note that we’re working on a new room for the Baby Adopter games so may be it is a good idea not to start over but wait a little bit until we’re ready with a new room?
