Okay, I actually feel through the other side of this now and asked myself the same questions over the last couple of months.
A first I thought it was all the pink and frills etc but actually, as lovely as that would be, I don't really mind not having it. I then thought things like ballet classes and Barbie dolls, but again when I really think about it, as much as that's a novelty at first it very quickly becomes another pain in the butt event whe you have to get to the class on time, have uniform day on time etc etc and the Barbie thing, well yes it would be lovely to give those things to a daughter but actually I would find it unbelievably boring to have to join in and play Barbie.
I d find girls tend to need more attention of you to play these things with them where as my boys just get on with it by themselves and this seems to be quite common.
Next up, I thought about my dh missing out on a daddies girl... I lost my dad when I was young and always loved the thought of my girl having the daddy I missed out on... Now, again, this would have been amazing to watch but we both know life would've been more stressful with a girl as she got older, especially if she has my temperament or even worse if she was like my annoying mother in law or sister in law..... Not sure I could handle that!
So with all those things off the list I was starting to feel better.
One remaining thing is that I do feel a slight embarrassment, I know I should care what people think of me but I know people will feel sorry for me having 3 boys and I don't want that... But hey, that's me giving a damn about what others think and it is superficial.
The thing I actually feel I will miss out on and it is sad is that I will never get a chance to pass down my womanly wisdom... Not ever... My boys can have tshirts saying "just like daddy" but I'll never have a girl to impart all the things on I wish I have know like little things like how to apply make up and then bigger things like realising that, that boy at 14 doesn't have to break your heart or that, that group of girls are just bullies, what they say doesn't count or that you are a strong woman, you can have anything you want in life.
So yes, it is sad that something so huge will be missed out on but I do find mums of girls stress over this stuff way more than us boy mums, they want to get it right to make up for what they didn't have maybe and there's part of me that feels relieved that I won't have that extra stress.
After all, I could pass on what ever tips I want - doesn't mean she'd take any notice, in fact, if she's anything like me, she wouldn't listen to a word of it and would see me as the enemy and actually I actually couldn't stand the thought of a daughter that doesn't listen to me - does that make sense.
I really feel its helped me see through my lost dream and I do think a boys life is way easier than a girls one and I look forward to the future.
I can't remember are you in the US? Fortunately sOme of the shops over here have the most adorable older boys stuff, when I look at the stuff my 9 year old niece wears its not half as cute as the things my 4 year old niece wears and the 9 year old gives my sister NO SAY what so ever in what she wears, she just point blank doesn't wear some of the stuff.
Hope things get easier for you x
