You can do this!
I tried this years ago with a group before I had the internet at home. Two years ago my son was born 2 weeks early in November and I did not make my world count. Last year my husband deployed to Iraq right before the month started. Again, I did not make it.
This year I am pregnant and due on November 14th, have a toddler and I am homeschooling a 8 year old. Oh, and hubby will not be home till near the start of the new year. Did I mention I am all alone here with no one to help? No family coming even to help with new baby around. Yet, I am excited to try yet again this year. I welcome the distraction. I welcome typing and thinking while breastfeeding new baby in the middle of the night. I am putting all other homeschooling aside for the month and my daughter shall be writing for NaNo as well everyday. My son can have his own note book and scribble in it.
I am a wonderful mother and all the better for showing my kids that it is ok to take time to renew thier own spirits and take time to follow dreams.
I can do the writing in 2 hours a day if I start planning now. I am having a homebirth with a midwife and I can write while in labor. (I went to choir practice when in labor with my son after my water broke. LOL) I will find time to write.
My problem right now, I no longer want to go with the plot Idea I had for the last 5 months. I have pregny brain and am lost as to what to write.

In short, you can do this and be a wonderful mama.
Blessings,
Kimmy
P.S. After all these years I do trust them with my work.
