Take it from this senior - good advice here, and I remind you work little by little at your shop, your family is first. Maybe find at least 1 hour a day to work Etsy - and tell yourself that's all I have to give. Let some of it mentally go. You are young and have time to build your Etsy shop as long as you keep it alive.
Remember, you can never recapture those baby and toddler moments, and what you do now creates memories for the rest of their lives :)
I wish you the best - relax and enjoy life!!! :) :)
