Today I was jealous of my childless friends because...

I have two friends from HS and they're both without kids... and traveling to AMAZING places right now (one is in Tokyo and another in Grenada.) Meanwhile, I'm attending kids parties, forcing my oldest son to eat vegetables (he's a picky eater) and navigating the toddler years with my youngest.

I know comparison is the thief of joy but I wish I had the income, time and patience to travel like my childless friends do. I'm pouring so much into work, therapy for myself and kids, daycare, etc... How do I get over this feeling?
