Our daughter will be 16 on Dec 27. We have never had 1/2 birthdays, we have always had her party on her day. We do separate gifts, I've never requested separate gifts but family members have always sent her bday gift in the package they use to send the Christmas gifts.There is a separate area set aside that is Birthday with Birthday wrap and decor. I feel it is important to recognize HER day, even if there is no gift, it is HER special day to celebrate.
When she was younger, she did get bday gifts at parties and I usually held some back for her to have something new later because it got overwhelming. As she got older, we throw bigger parties and we put on invitations "no gifts please" or to bring something to donate to the animal shelter or food pantry.
She loves parties, I love planning them so they are a celebration for her and her friends. Since she turned 13 we'v e had parties with DJ, dancing, food, etc. It is amazing how many parents are ready for kids to be out of the home just 2 days after Christmas. I've had as many as 80 show up for a birthday party.
2010 will be different because her bday falls on a Monday and our country club is colsed on Monday's (that is where we have the parties) so we are planning her party for early January for the first time but it is a big one, Sweet 16!!
