I started a few days ago and I've been using the Frida Mom Prepare to Push Wand to do it. It is possibly a bit expensive for what it is but much easier than using your thumbs!
I've bought the aniball as I wasn't sure about doing the massage and thought that might be easier!
I've never done it. Three babies and no tears x
Do you have a partner? If so, definitely get them to do it. My partner did mine last time with olive oil and I swear was the reason I didn't tear too badly with my huge-headed son. My partner will definitely be doing it again this time!
