Talk to General Physician on Mosquito Bite Marks On Legs

Salam. My 1.75 years old daughter is quite susceptible to mosquito bites and has had a lot of them on her legs in the past 2 months. She's otherwise fine but has a lot of mosquito bite barks on the legs. Is there any non steroidal way to get rid of them? I've been applying vaseline and coconut oil sometimes (as it's hot in Lahore). Please help. Thanks.
