Thanks Suzie! The retainer fee is a good idea and one I hadn't thought about!

The reason I asked about claiming is because I don't use the formula. Half my home is daycare only so I am able to claim 50% on most things. Using the internet for example for dc purposes (art ideas, emailing about dc, activity ideas etc) is something I would still do all summer. I am thinking I will have to deduct some over the 6 weeks I'd be closed. I will talk to my accountant this year about that
