My husband belittles his efforts on D's dress and hair but it's a GREAT opportunity to reinforce his efforts. Remember, failure of ALL kinds is an issue with men. I've noticed my husband is often saying, "D's hair is a wreck, I'm sorry". I try to build him up (without being too overly obvious) and you did just that. It may seem small but knowing you believe in him is often a big deal for men in general.
Remember, there will be more confusion, more not-so-fun interactions. I hate to be THAT reminder but the truth is you have THIS interaction to remind you that it goes back and forth. Focus on the good.
