I think I have the same thing

My 10 yr old has never had a bday party cuz I can't get it together (or this year it was cuz his brother was in the bhu). But I am a chronic procrastinator and I hate that. I can be so indecisive. I get anxiety about planning things with people cuz so many times i have flaked due to "not feeling well".
With my older kids, we did do some bday parties and it was usually me calling the families sortof last minute. But I see other moms do that too, they just say, "I know this is a bit last minute but we'd like to invite you to "Tim's" bday party."
Can hubby take care of this one for you? It's gotta be a bit more overwhelming with the new baby. Give him a good pat on his chest so he can feel extra manly for taking care of you
I don't know if any of that helps, here I am procrastinating work I should be doing! But I know you'll pull it off and it will be a happy day for your son
