I agree with needing more help (and I dont have any twins just yet!)
My husband and I work from home but he is only so much help before I lose him to youtube
I am actually actively trying to find someone who can come over 2-3 times a week to help with things like laundry, cleaning, shopping and just giving me a 'break' for 30mins to an hour so I can be alone or shower or go for a walk etc.
I found with DS (we had no help for the first 2 years, he is/was literally with us 24/7) a lot of times I just really craved the chance to shower alone or to go for a walk outside without bringing him or heck, even just go to the grocery store solo! Not sure if that is/was 'normal' but for me it was very much an important part of feeling balanced and able to be a good parent when I was with him the rest of the day.
So although I dont have the twins yet- I am planning more then anything for some sort of twin stroller and someone to help for the first 4-6 months until my oldest goes to preschool a few times a week so I can look forward to some down time. .
