To think these hours might be too exhausting?

[PregnantAndEngaged]

I am back to work off maternity leave on Monday and I'm a bit concerned I've not asked for my hours wisely. At the time I asked for them I was thinking of spending maximum time with my son and reducing expenditure on childcare as my partner could look after him in the evenings.

Monday: wake up at 7am, look after son until 1pm, travel to work from 1.30, work starts at 3pm until 9pm, travel home and get home at 10.30pm.
Tues and Weds off but looking after son
Thurs: same as Mon
Fri: same as Mon
Sat and Sun off, looking after son but can delegate some responsibility to partner.

Note I never get a lie in as he wakes at 7am without fail. I appreciate I still get 4 days 'off' though and I think this is why I chose awful hours, but I'm feeling shattered and I haven't actually started work yet. Starting to feel stupid for choosing the hours I did.

Someone tell me this is manageable and I won't be completely exhausted and run down!

It might not be as bad as you think. I work full time and have a 1.5 hour commute each day. I get up at 5.30am every weekday and I'm completely used to it now. I LOVE my commute. I get to read books/magazines/newspaper without little people nagging me or climbing my legs, play on my phone, have a cheeky can of gin and tonic on a Friday evening etc.
The "childcare" outside work is fine add I miss them so much when I'm at work I make the most of the time I spend with them.
Your partner must let you have one of the weekend lie ins though. That was something I absolutely insisted on when mine were up at 7. (They are now lazy buggers who like to snooze until 9 at the weekend so that may well improve over time for you too. )

*each WAY

It will take you a few weeks to get into a routine but it's totally doable. And I'm jealous!
