Children's Book - Sick Child at Work with Mom

When I was a kid in the 90's, my parents read a book to me that I thought was called "Ah Choo!", but Google is failing me. It's a fiction children's book about a kid who has a cold or something and goes to work with mom, and has some adventures there. The illustrated cover of the book iirc was a kid under a table.

I've been looking for this book for years so would love some help finding it for my own kiddo! TIA :)
