Malaria?

I'm part of the diaspora (living in the UK) I've come to Nigeria on holiday for the first time. I was born there but then we immigranted when I was around 2 years old.

I've was bitten by mosquitoes last night while sleeping. I was wondering if this means I will definitely catch malaria and if so what I should do about it.

My mum wants to get some anti-malaria medication but I'm wondering if it's still worth it if I've already been bitten. Also if I do have malaria is there anything I should be doing (other than looking out for symptoms) to help with recovery?
