OP
Its good you are set in your decision and are happy with it. Not sure why you posted here if you are so happy with the decision.
ou should do definately what you think is right for you however there are lots of interesting and helpful comments on this thread that are worth some thought.
The thing that comes out from your post is that I think that you are still in world of maternity leave (I think- sorry if I missed how old your child is) going back to work is huge upheaval that a lot of people would want to avoid. However- without trying it how do you know its what you want- for sure?
Not wanting to go back/ leave child in day care is very common. There are a number of threads in this section (and I probably started one myself last year) about ladies not wanting to go back/cant face leaving DC - as thats a natural response I think- the simpler solution is to stay at home- less stress/ guilt/ pressure etc (although harder in the long term for sure). Espeically when maternity leave is a bit like a long holiday so a novelty. But long term being a SAHM is huge commitment.
Im not articulating myself well here but what Im saying in your shoes I'd go back for 3 months and see how it goes. Then make a decision. That way less bridges burnt and you can really see how it works out.
I am/ was in the same situation but the opposite- I went back to work full time in January. Me giving up my job or even droppping to 3 days/wk would mean us moving to a tiny flat and changing our lifestyle completely. None of which is bad but it wasnt the choice we wanted for our family.
I dreaded going back, didnt want to leave DD in childcare, had regular meltdowns about it. But I did, I got through it and found that while there are huge pressures being at being work, being "me" again is the best bit. Im not just someone's mum.
I'd happily drop to part time now and most of the time Im sucking lemons that I have to work full time but I know I couldnt be full time at home.
I've waffled on but hopefully you get what Im trying to say.
Good luck with your decision and being at home.
