Just my 2 cents - because no one should be made fun of and it cheeses me to know people do it - I felt the need to respond.....
Now, I do not have a daughter, but I do have 3 nieces, stepkids (sorta) and it's not just Disney customs that get comments, it's everywhere/everything. I get flack about what I do for my son and is this my take on it. (Now I talk real plain so I hope this makes sense.)
Anytime you do something that is over and above or what others wished they had the gumption to do with their kids but don't - you will get slack. The way I figure it is is this... these are your babies (1 year old or 30 year old), and you do what you do because it comes from the heart. Well two or three hearts really when the love of whatever you are doing is being shared between you and your children. I say as long as the kids enjoy it and it makes special memories who gives a flip what other people say. I say they need to take a look a themselves and try to remember the last time they saw a twinkle in their kids eye because of something they did. It's enough for some to parent by providing food/shelter/clothing to the children and make special time for themselves so they don't lose themselves. And, there are parents (like me) who would rather see the twinkle and make a memory than give a hoo ha what the others think. When it comes down to it, I have to tuck my kid in at night and know I am the best mommy to him. Does he have more than me? Yep. Does he get all the handmade whatever I know how to do? Yep. Do I bake/make/take things for him to school that others may joke about? Yep. Do I get laughed at because I am not an "IN" mom and wear old sneaks and beat up jeans? Yep. Do I give a crud... Nope... That is all that matters is my kid is happy, healthy, and LOVED. Period. And, anyone who wants to flame me from the other board or whatever can feel free to. If that is what makes them feel better than go for it because in the grand scheme of things they do not matter, never have, and never will.
So, disregard those who think this is wrong or bad or whatever. They should spend the minutes they take ripping people apart to look inside and see if they are trying to make themselves feel better. Chances are - they are. If the energy was spent doing special things for their kids the world would be a better place. Kindness and love would replace hatred and jealousy.
So, now that I have rambled (and not cussed once, I am so proud of me!) keep doing what you are doing. Make the dresses that your children will remember, make memories that others won't have, tuck your kids in bed at night, say sweet dreams and know you are being the best mommies you can be.

Oh, as a postscript, I am also a momma bear who will rip the face off anyone who hurts my kids (son, neices, stepkids, etc.) so this was written in a manner not to offend anyone - ~fluttering eyes~ LOL ~ I hope I succeeded, if not let me know and I will delete. Off the soapbox now and exiting the building....
