To make the correct probabilistic comparison, you'd need to know child mortality rates among 1-year child group and 2-year child group. If you want to compare baby boys only, you'd need to gather data for the boys, excluding the girls.
A lower age doesn't necessarily correlate with a higher survival rate. In UK, for example, under-1 age group has much higher mortality rate than 1-4 age group, which has higher rate than 5-9 group. It's only after 50/55 that adult mortality rates start exceeding under-1 group rate. This might vary from country to country. So you need specific data for the specific group from a specific country/area.
