How do you deal with sleep deprivation .. While baby is growing up once in a while not getting enough sleep is a part and parcel of motherhood. I keep myself hydrated , don't think too much about how tired I am , try and get naps as much as I can. Also avoid being snappy at others cause it's not fair.
I would nap as much as I could while they did. Sure the house was a wreck, but it's better than falling asleep accidentally.
