dating a young mum, tips?

ive been with her since around November, she was a friend from my polytech a few years back, and she has a 14 month old son, with an ex friend. im happy with her, shes amazing. we are primarily long distance, though we only about a few towns away from each other. im very happy with her, but im still getting used to all the mum stuff, though im accepting that hes her priority, yet i feel that i could be doing a better job. while im not living with her, i feel like i really to try be a better partner, especially if we go further
