When my kids were small we had Nobody's Birthday parties because we loved birthday parties. LOL. We decorated and had dollar store gifts for every one to open. The kids still talk about our Nobody's Birthday parties. No need to be so silly as to stick with a date on the calendar. We have Thanksgiving meals several times a year. Each one has different relatives or the same ones. Same with Christmas. My kids have Christmas at home with their kids, we have Christmas on New Years most times for the grandkids. Work and rest come first for most young families not packing up to drive to eat and shame on moms and grandmoms that insist.
