And you may have to wait even more after that until someone who wants to open one shows up, if you're one of the unlucky people (unlike me =p).
Yeah, I've seen people approaching Rank 30 and still not have a Nursery.
I've had my second gym leader visit today, this time, it was Elesa. A few days ago, Drayden had visited. Loving the 1000 points they give, especially if I'm able to send them to my nursery, which is still at a lower rank, since I had to wait quite some time before I got it. Unfortunately, Elesa wanted a shop with a female clerk, my nursery is run by a male clerk
