Milestone Stickers

Currently at 35 weeks pregnant and wanted to design something for baby (really for me, haha). Our nursery is outer space themed and we don't know the gender, so it's been a bit of a challenge finding things that are bright and colorful, while still feeling neutral. Why is so much baby stuff so boring???

Most of the milestone stickers I've seen online are just not my style: too preppy, or plain, or pastel.

I didn't design the planet icons, credit goes to Brian Ondari.
