Really hoping some of you are up at this time of night to offer advice / talk sense into me.
I'm pregnant so may be partly hormones but i can't sleep, having a massive panic attack over how we'll afford things when baby comes. Would love some solid advice not just 'oh you'll manage, everybody does somehow'.
DS (4) has got a school place from sept 4.5 miles from our home. Before & after school clubs would be £60 pw which is obviously very good (if only paying one childcare) but apart from cost there's a waiting list so no guarantees. The school is in the opposite direction from our work - so 20 min drive there, 30 min drive back the opposite way. I currently don't drive though am trying best to learn fast. DH works 1 hour away. Both of us have standard 9-5 hours.
DM moved up here recently and had said she's do wrap around care for which I know we'd be v v v lucky. She's now said she won't (she suffers a variety of mental health issues). Full time childcare for baby at 6 months old (meaning 10 hours per week from 6 months, no option at my work to go part time) would be £250 per week. Add to that the wraparound care for DS = £310 pw on childcare, not accounting for school holidays.
So...£1343 per month on nursery & school clubs.
We have considered a nanny but they all seem to charge £10 per hour, making it considerably more at £2166 per month, if we could find one.
I earn £1700 pm after tax, DH £2000. DH's salary is currently used up - almost to the penny - on mortgage and bills. Mine could pay for nursery/school clubs with £300 pm over, it couldn't afford a nanny.
Even with the nursery/clubs idea not sure how I could physically pick get/pick up baby from nursery and then do the 4.5 miles to school within school club constraints of 8-6 and work constraints of 9-5. & I don't currently drive.
Obvious answer seems to be - become stay at home mum. Which i'd hate as I love my career. But obviously children come first. However, if we did this, DH's entire salary will be gone on mortgage/bills, we'll have nothing at all left except child benefit. Not sure how I'd afford to run a car / bus fares to get DS to/from school 4.5 miles away, no chance of moving closer if I leave work as can't get mortgage without joint salary. DS costs us an additional £70 pw in petrol as his dad lives 2 hours away & we do the journey to drop him off (exP brings him back) every week...not sure how we'd afford that.
Please please help/advise, can't stop crying or get my head around it 
Sorry for long post....
