I used to live in Sri Lanka and travelled there with my daughter when she was 3 months old staying for 3 months. The driving there can be shocking so make sure if you hire a car and driver that the driver understands you want to go safely not quickly! Definitely take your own car seat. It will depend on the time of year you are going and if you are into surfing which beaches are good for you some have a lot of waves but you can find the right beach whatever you are looking for. The hill country is cooler and easier with a baby in that respect, I climbed up Adam?s Peak with my daughter in a baby carrier which was amazing. In terms of food, you can find anything there so you shouldn't have a problem. My daughter wasn?t on solid food at that time (though we have been since when she is) none of my friends with babies there have any issues when staying in hotels etc. Pm me if you would like any more info.
