Your Guide to Online Mommy Lingo and Abbreviations


I got into online Mom groups about six months postpartum and loved it! I never saw myself as someone who would partake in online discussions, but the unique experience of becoming a mom changed all that. It can get lonely when you first become a mom. No matter how close you remain with your non-mom friends, there’s a definite need to connect and bounce ideas off other women going through the same things as you. I had no idea how many moms out there had the same opinions on parenting as me, and I got some amazing advice. Within mom groups, you’ll find yourself advice, opportunities to teach others, connection, and commiseration.

Mom groups have their own lingo of acronyms, and it almost feels like a foreign language when you first get into forums. So I’ve typed up a list of common Mommy Lingo to help you get a head start! I’ve divided the lingo up into five common topics you’ll find in the groups.
