I went back to work when LO was 10 MO. She is now 2YO and it has got even more tiring not less so. I work 4 days a week on 80% salary and it just about works but it is really, really tiring. We are up at 6 and leave hourse at 7am so I dont watch TV during the week; I go to bed as soon as lunchbox/bag etc is ready for next day, basic chores are done and I've had a shower (around 8:30 or 9pm) and we all go to bed even earlier at weekends! This is the only way I can make it work. It's tough though, and basically there's no way around it - I think you just have to get used to it!!
I am focusing on being shattered during the week, so spending my weekday evenings doing bits of housework, getting meals ready etc., so that I don't have much to do on the weekends but be with the baby. It's sort of working.
another shattered one here I am afraid- my youngest is 2 - that said I have had a quite a bit of time off - 2nd maternity leave and 6 months not working very little and I was tired then so I think its more the parenting than the work...there was a good thread about being organised and working full time might be some good hints there
This is not going to help at all, but my last daughter is 3 years old and I only work 3 days but at the moment I am absolutely shattered. I think it will get better but it still goes in peaks and troughs - the absolute key is to find a way to cope with the troughs, which is something I still struggle with. I talk about giving up work everytime I hit a downturn and start to feel exhausted! Hopefully someone will come along with more advice!!
