Do we have toddler strollers yet? Taking toddlers to the Festivals and bathrooms too

I was wondering if you can get the toddlers out of the apartments and down to the Festivals in some kind of stroller? I know we had them in Sims 3. With all that activity going on out there in the city seems strange your kids have to stay in the apartment. Of course, once they are down there the bathrooms should be accessible for the little ones otherwise their needs would be a real nuisance if you had to run them back to the apartment whenever they needed changing.
