I don't blame you, my feelings would be pretty hurt too. Men just sometimes don't think like we do and unfortunately, we occassionally have to spell things out for them, in the nicest possible way so their egos don't get damaged. If he really doesn't know what to do for you on mother's day or feels uncomfortable doing anything (I know, silly, but possibly true), then passive aggressive comments about other people honoring you or being pregnant for 10 months isn't going to get you the end result you really want.
I'm going to suggest a different route here...maybe make sure his Father's Day is special...simple, but special. Get him a card, have your daughter do a homemade project and card. Maybe the two of you could come up with a list of what makes him a great dad. Plan a day that he would enjoy...maybe make breakfast in bed or a favorite dinner meal. I wouldn't get an elaborate gift or plan an expensive, busy day.
Then maybe a few days after Father's Day you can ask him if he enjoyed his day and take the opportunity to say how you don't need anything huge, but something similar would really be special for you too. Sometimes men need you to specifically say, I'd really like to go do X for Mother's Day and then I'd really enjoy a meal at our favorite restaurant, in order for them to actually do it. I'd stay away from "you did this and you did that" kind of talk and focus on how it would really make you feel special to have a nice Mother's Day and how wonderful it would be if the three of you could come up with some nice things to do on both Father and Mother's Day that could be a family tradition. Not only should you honor each other for all the hard work that goes into having a happy family, but you both want to set a good example for how to treat each other...I mean, you wouldn't want your daughter to grow up thinking that she won't deserve to have a special day when she someday becomes a mother, right?
If taking an open, honest, nonconfrontational approach doesn't work, then you may consider a counselor. I suspect that treating you this way doesn't just happen on Mother's Day. And I could be wrong, but it would be very strange for him to be an excellent loving husband 364 days a year and then on Mother's Day he decides to be unappreciative.
Good luck.
