You never know when the shop going to open. Sometimes he'll announce it's open for 3 days and you can go anytime you want in those 3 days. Other times he'll yell at me from his upstairs room while I'm making dinner or working on something that the shop is open, but will be closing in 10 seconds so I better run.
As Tessa is getting bigger, the "free baby-sitting" part of the shop becomes more and more valuable. He'll read her stories, bring her toys, and wrap her up cozy in a blanket. He will even scratch her back when she gets fussy.
Now if I could just talk him into adding "toilet scrub" and "bedroom clean" to his shop inventory!
