Missed my friends baby’s first birthday party

My 2 month old son had his vaccines two days ago, and today his fever finally went down, but I can tell he still isn’t feeling well because he’s been cranky and still spitting up more than usual. My friend lives an hour away, and I haven’t went by myself that far with my son yet. I would have asked someone to go with me but my husband had to work, my mom said she was going out of town. I feel horrible.

I told her why and she read it but didn’t respond. She rarely got out with her son until he was around 6 months. Surely she understands.
