Hello SB. I am a mother of 4 and have been doing a PhD in a 5-star rated university department. It is very hard. Far, far harder than I ever thought.
Academia is a dog-eat-dog world, where mainly men enjoy cutting down their peers. Research is a very personal thing and so you deliver your paper and then everyone enjoys criticising it. You have to be very robust in your responses. It's a very masculine experience. I am doing an arts/social science PhD. The scientists are more consensual as they work in teams.
The Senior Common Room is very lonely for a mother. The lecturers and research students do not enjoy talling about anything normal and spend their time point scoring - it's a strange experience and not very pleasant.
Most of the PhD students are in their early 20s and so, socially, you will be completely different. This is isolating but manageable.
The PhD is very difficult. You have two advisors, who send you up research cul-de-sacs and so there is a lot of time wasting. You spend hours and hours on the research for very little reward. Everyone is out to criticise you. If you have a supportive advisor, that is great but then the advisor him or herself is up for scrunity and sometimes can be given a rough ride if you are not up to scratch.
You are expected to conform to a standard (e.g. academic language) and if you vary from the norm, it is a struggle. Research goes in fashions and if you are not fashionable, things are more difficult.
You have acres of paper and, worse still, Internet sites to plough through and just when you think that you are getting somewhere, the goalposts change. All this is very difficult when you are looking after young children as well.
If I had my time all over again, I would sign up for a PhD with the Open University because they are used to students with different lifestyles.
When I embarked on my PhD, I really thought that I could do it. I have close family at high level university positions, I have a good degree and an active brain. Nothing prepared me for the uphill task. It is do-able but you have to be strong and very committed.
In my university, many many PhD students fall by the wayside. Mature students rarely get through the hoops. My best friend, who is a scholar and has no children to distract her, submitted her thesis, had a viva and has been told that she has one year to resubmit it. So even when you get nearly to the end, goalposts are moved.
I am an optimist and I believe in following dreams. So go for it but be aware that it is a very bumpy and arduous route to take.
