Mommy Domme Tips

My boyfriend and I have been dating for several months now and we've always been big on a daddy/little sexual relationship, but recently he's been very keen on trying a mommy/little sexual relationship (he's a switch). This has been tough for me because I'm VERY purely submissive, and I just don't know what I'm doing when it comes to being dominant. I was wondering if anyone had any tips on being a good Mommy Domme for him and what I could do to get better! Thanks! 😄
