Hi OP. First of all, congratulations! Secondly, you are only 12 weeks PP. You don't need to make any decisions yet. Leave it as late as possible.
Like you, I work for the NHS and toyed with the idea of giving up work to look after DD full time. I went back and forth on it for months.
I am now 11.5m pp, and I will be returning to work! I made the decision around 10 months. It was an easier decision than I thought even though I was in tears at the thought of it when she was smaller.
My reasoning is:
I'm the higher earner and have big potential to scale up my career long term
NHS continued service!!! I only have 1 more year before I hit 10 years service and get all the benefits of that. I didn't want to lose that.
Pension!!! You just don't know what will happen in the future. You won't be able to pay into the NHS pension if you don't work there (obviously).
My DD is HARD WORK! Now that she is eating 3 meals a day, crawling EVERYWHERE, climbing etc - gone are the slow days of cups of tea in bed and leisurely strolls with the pram! I am looking forward to having a hot cup of coffee and some adult conversation 😂
I accrued my annual leave and bank holidays, so I'm going back part time using annual leave for 3 months. After which, I'll reassess the situ.
Nursery - I used to work at nurseries so have seen how incredible they are, how well kids do, and thrive. I did actually work with BH before and they are very process driven and strict, so I was utterly shocked to see the news today.
My DD is so social. She has enjoyed her nursery settling in days. I WFH so I can drop/pick up within 5 mins of starting/finishing work.
At the end of the day you need to do what's best for you and your family. But I would definitely encourage you to wait before making any big decisions.
Also, a note that if you quit your NHS job during mat leave or within 3 months of returning, you will need to pay back your enhanced mat leave pay.
