I work Friday and Saturday nighs - 12hr shifts. In all honesty is really wipes me out! I get up between 5.30 and 6.30am on a Friday morning with the girls' then don't sleep again until I get home on a Saturday, I usually manage 2/3hrs before the girls' wake me up if I'm lucky I get another couple of hours then I grab a shower, something to eat and back to work. When I get home on a Sunday I have a nap then its our family day. I work from 19.00-07.00. On a monday I'm still so tired. I couldn't do anonther night tbh dd2 is 17 months and I can't gurantee she will nap. Good luck x
