My lifestyle now is relaxed. I get to see my family a lot, go out, see friends and have time at home. Medical school was just study, study, study all the time, but I found medical school harder than my foundation programme.
I became a dad at the age of 23, so it coincided with FY1. Looking back, it was probably better that I had all the 'busy life' all at the same time and I'll admit it was hard, but I have to thank my family and friends for helping me with childcare etc...
I became a dad for the second time a year later at 24, so FY2 was the same as FY1, but with added pressure at work.
My missus was a band 5 nurse at the time and her ward manager was fab and very understanding with our situation, so we were able to adjust her shift pattern to make sure that when I was working, she was either off or working nights if I was on days for example.
My missus is a doctor now. She originally applied to medicine, wasn't successful and did nursing instead. She's just finished her FY2.
I'd say you could manage studying and kids together as long as you've got the option of help when you need it. I was/am very lucky to have the support I had/have.
I have a bit more freedom now and I like to get all my hours into 3.5/4 days so I can have a good bit of family time.
