I have just in the last three months increased my work due to staff chnages and do four days a week 10 hours days and it is busy. I'm usually cooking dinner the minute I walk in the door! My DS helps out with the cooking so we still interact and we eat and then have bath and bed. So mon-Thur is really busy.
I also have a cleaner every fortnight as well which is fantastic cuz it just wasn't getting done.
I don't feel as guilty working the hours I do cuz DH picks our son up from daycare when he finishes work at 2pm.
