Also to know is, is it worth staying in Sorrento?
We love Sorrento. We've stayed there 3 times, for a week each time. For us, it's very fun, very charming. Love all the other places to visit (Amalfi, Positano, Herculaneum, Pompeii, Mt Vesuvius) but do not care for Capri at all (been there at least 4 times).
Also Know, is Sorrento safe to visit? Generally speaking, Sorrento is not a too dangerous city for tourists. They need to have in mind that demonstrations may occur and they should avoid any protests or political gatherings so as to remain safe and sound.
Herein, which is better to visit Sorrento or Positano?
Sorrento is a nice but quite crowded city. Positano and all the southern coast is much more typical. You could consider also Amalfi, more flat than Positano, with a pedestrian zone, better for a baby. If you are interested in beach, Amalfi/Sorrento coast is not the best option.
