Don't feel guilty at all. One on one time is good for kids.

I love the time I get with my toddler as I miss him heaps. It used to be just him and I when I was on mat leave and now I mainly look after the baby so I miss him.

I love my one on one time with my baby as I sometimes wonder if he missed out on so much because he never got as much when he was little. And he's so much fun to play with!
