DD 'attended' a zoom bday party for her friend yesterday... they did it at 7 p.m., and each kid had their own dessert, so they could all sing to the bday kid and talk and eat. Lasted about 45 minutes.
I've also been seeing a lot of bday parades on the news, where parents arrange for their kids' friends to drive by the house with signs, balloons, a siren, etc., honking, and wishing them a happy bday. Brought tears to my eyes.
I agree on doing whatever you can to make it special at home- the night before my kids' bdays, I put crepe paper/ streamers across their door, so they have to bust through it in the morning when leaving their bedroom. (You could also attach balloons.). Have balloons and bday banners hanging up in kitchen/ dining area. Balloons of their favorite colors attached with ribbons to the bar stool where they'll sit. I use a red "You are special today" plate for them. Card on top of plate. They pick breakfast (crepes or bakery donuts are popular with my kids), lunch, and dinner. Have siblings make them a card. Order your stuff from Amazon now; hopefully it'll get here in time.
Phone calls, video chats, cards in mail, e-mail messages- all of it is even more special and precious now, IMO.
Happy Birthday to your sweet daughter!
