I have also had occasions where my husband has continually forgot things i have told him, it seems to be a common thing for MLCers to be forgetful. In future i would not remind your husband that he is being forgetful just let it go. I am sure your husband appreciated your apology and thanking him for having the kids longer.
Take care
