I think it's going to depend on how well you can manage your time & family life
- make sure that your husband is fairly competent in domestic matters - cooking dinner, and stopping the house from falling apart, and if possible teach your children some basic life skills like loading the washing up machine.
- make sure that your children are in a good bedtime routine before you start uni, so you can reliably study when they are in bed.
- make use of any time that you have between lectures & seminars to go and study in the library
- investigate after-school clubs in case you have lectures / seminars that finish after they finish school.
It's perfectly doable - you're far from the first person to do it, but time management will be the key
