When I first started - I did a couple of interviews during daycare hours (after getting permission from every existing client first). Each interview was a flaming disaster. I couldn't talk and carry out a conversation with the daycare kids vying for my attention and then they acted up. It was impossible to have an adult conversation about policies and rules and have noisy kids underfoot and playing things up for attention.

I never ever do an interview during daycare hours now. I don't care if that parent decides not to sign with me - but it will just not happen again. Either way it is a lost cause IMO.

I interview in evenings or weekends.

I don't allow parents to come in to transition the kids either. I don't understand how it helps to have the parents here because eventually the parent still leaves. The child may actually be more confused why the parent stayed at first and now isn't or where they went. I am totally a believer of quick drop offs especially during the first month. I always set the parents' expectations during an interview about what it would be like the first month with quick drop offs.

I do offer transition days where the parents can drop their child for 2 hours, then a half day and then 6 hours and then 10 hours. I charge for this. I am not sure if it really helps but it tends to make the parents feel better and it works for some kids depending on personality.
