[Monterrosa-24]

“...deduced from that that Jesus would be around 2 years old...”

Herod made no such determination that the child would be two years old. His declaration was that all male children two AND UNDER would be destroyed. The Wise Men found Jesus in Bethlehem and there is no reason to believe that he would have stayed there for a long period of time.

[Antoninus]

The Wise Men found Jesus in Bethlehem and there is no reason to believe that he would have stayed there for a long period of time.

If you've ever tried traveling with a 1 month old, you know what a bad idea it is. Now imagine doing it on foot or on the back of a donkey. It makes sense that the Holy Family most likely remained in Bethlehem for some time and the Magi found them during that period.
