My Dad was a December baby & would have been 95 next week. . A good friend who sadly died earlier this year was a December baby.
I do happily have cousin who whose birthday is at the end of the month.
I don’t have a December birthday but my granddaughter is “Sweet 16” today.
My Daughtier was due Christmas Day but came 10 days late. We always celebrated as a family but I gave her half year birthday parties a couple of times for her friends.
