I've got one too, its my fisrt time though and I haven't connected to anyone yet, so whoever said that is probably right, I have tried to take good care of it and dont let its hearts fall down too far
I got a yfotchi by not letting the hearts go below 2 and always cleaning it's messes right away, the connecting thing isn't correct, I connected my V1 with V2 all the time hoping they would mate (they did) from the time they were babies so the not connecting thing isnt always right.
