I am full time but over three days. I returned to work when DS was 10 months old. He's now 16 months old.
Due to my shifts, on those three days I only see DS for 20 minutes. Those 20 minutes are in the morning before I leave for work. I don't get home until 9pm so he's obviously in bed by then. I don't particularly like it but that's just how it is.
Sometimes, depending on my shift patterns I actually go 48 hours without seeing DS and that's really hard.
Of the 3 days that I'm at work our DS is with a childminder for two of them and with my DH on the third.
The silver lining to shift patterns is that although I find the three days I work really difficilt as I hardly DS it means that he's with me for 4 whole days a week and I class myself as lucky to have that.
My previous job was 9-5, four days a week, but I resigned when DS was 6 months old (I was still on Mat leave) as I couldn't bear the thought of being away from DS for that long and they wouldn't let me reduce my hours.
I then applied for my current job, which I obviously got, and it suits me much better.
