My mum was a mature student and didn't go to university until she was 28. But she finished her degree first and then had me when she was 33. Maybe you should consider finishing university first before you have children instead of disrupting your studies intentionally? I don't understand why the rush to have children so quickly when you have something else to focus on first. What happens if you have your child and then need to defer for more than a year? Situations like this are how people end up leaving their degrees early and not going back to finish them until much later in life, if at all.
