I haven’t been pregnant at uni, but I have done a degree and later had three children, so I know how demanding each is and I wouldn’t have wanted to do them at the same time. Having a baby really takes over your life, and it’s hard to focus on anything else for a good year or two! You could get bad pregnancy sickness and be unable to function for months, and once the baby is here it usually takes a good year until they’re sleeping through the night and you’re not operating in a sleep deprived fog! Babies are also a big stress on relationships because you’re both grouchy, tired, poor, and have a sudden lack of freedom and no free time.
Having said that, having children is wonderful and I’m glad I have them, of course. But I would not combine it with taking a degree.
Depends on what you’re studying and how demanding it is really. My first degree was in nursing which invoked 12 hour shifts when on placement, you can’t leave a baby that long especially if breast feeding. You have to think about childcare, who will look after baby or toddler when you study. My youngest is 1.5 and I’m studying another course at the moment and I can’t get a single thing done with him around! All my studying has to be done when he is napping or in bed. So I have no leisure time.
27 is still young, it’s absolutely fine to wait til 30 to have a baby, most people I know had their first baby around then.
