It's guaranteed to be that way.

There are strict rules in filming regarding using children, and especially infants. Plus, they're hard to work with and shooting them for extended periods becomes costly and time-consuming.

That's why, in TV, the babies are rarely seen, and often jumped up in age to the point a child actor can be used.
