I'll be travelling with Ryanair to Croatia next summer by which time I'll have a 3 month old. We'll need to take some kind of buggy and I guess a car seat (bit concerned about the quality of car seats you get with rental companies).
I've been lent a very old Mamas & Papas system which has a big wheel base then a carry cot to go on top. There's also a pushchair type attachment but it doesn't go at all flat so not sure is suitable for 3 month old. Plus, Ryanair will only let you take a buggy or a car seat. Advice needed!! If I have to buy something new I will.
