Does anyone have any tips for how to learn a new language and stick to it whilst working four days a week, raising a toddler and trying to fit in housework etc?

I am going to attempt to learn Scottish Gaelic (hubby is a native speaker and we want to teach our little fella to speak both languages!). I have a 'teach youself' kit... i was planning to read ten minutes a day of it while i am on the exercise bike once Angus is asleep. (Ten minutes a day is about all the spare time i have!)

Any tips greatly appreciated!
