When I started med school, he was 1.5 yo, and now that I am starting res, he is 5.5 yo and starting KG....he doesn't really know the difference, however, now that I am finishing my third call shift in 6 days, he was disappointed that I wouldn't be home tonight. But it is the last call, so we will have more time together. Earlier on, when he was 2-3, it was hard, lots of hard goodbyes. But now it is much easier. It is important to be there for your child, but they must learn that they are individuals in a household, not the center of everything, that way, they do their thing, you do yours, and sometimes, you do stuff together. We get along just fine. Now everyone wants to know, when you are going to have another one! Family and med school are possible, but definitely not easy. Having a supportive spouse and lots of child care assistance is key. Thank goodness for grandma!😉
