Advise please first time travelling abroad with kids

AZ

I’ve never travelled abroad with my kids… where do I start? What are the essentials? Help please

We are going to Turkey for 7 nights, me my daughter (2 years old) my son (9 months old) and my husband.

Please give tips on feeding, plane journey, going in the water, etc. is it worth getting a double buggy or are 2 singles fine?
