Slow and steady wins the race.
I have 5 kids, my youngest was 6 months old when I began prereqs, and I have a 4.0 so far. I’m half way through physio with an A+ so far, and only have micro to take after this.
If you need straight As, it’s crucial you do not overload yourself.
Doubling up on your sciences is tempting to get through them quickly but unless you can make school your full time number one priority with no other obligations or are already very strong in the areas, I’d never ever recommend it.
I personally also took even more time by taking some remedial math and chemistry before I got into the real prereqs. Being totally secure and set in algebra set me on a smooth path for chemistry. Being strong in chemistry and algebra made nutrition and physiology easier. Take your “easy” classes over the summer to speed things up if you want to, but I see it often with classmates every semester, the hurry-to-finish overloaders either drop something and have to have a W on their transcript, of have to face Bs or Cs in an area so impacted they’re simply not in a position to be as competitive.
And also, let me tell you. I think being a parent is a benefit to you as a student. For me, it forces me to never procrastinate so I can get everything done. It forces me to do my best work because I have 5 daughters watching me and they think their mom is smart and I’m motivated to not let them down. You already know how to work through tired and do hard things you don’t want to do if you are a parent. You don’t have time to waste . You bring a set of skills, organization, and dedication as a non-traditional student. Use them to your advantage!
