Postpartum wrist pain/ Mother's Thumb?

Ellie💌
Hi ladies - anyone else have postpartum thumb/ wrist pain!? I had my baby 3.5 months ago. Apparently this is a common problem for new mommies due to all the baby lifting :( I had no idea this ailment  existed but apparently it's a form of tendinitis often called "Mother's Thumb." It's worse in the early morning - the pain shoots down from my thumb into my wrist. I can hardly lift baby out of her basket to feed her! The doctor prescribed a splint, and I've been icing it, but I wondered do if anyone had other tips?
