When he comes over and your girl is being fussy, just hand her to him. I dont know how old she is but I would say something like, 'You showed up at just the right time, Alexia is a little cranky right now do you think you could watch her while I get her bath ready?' or how about ' I was just about to run to the store for some more wipes, since your here could you babysit for a few minutes. I'm sure she will want to spend time with you since your here even though she gets cranky about this time.' After a time or two he might lighten up.
