Economical family car

Hi together. I am looking for a car for my small family (woman + two small children [one 2 years old and the other 2 months old]). Criteria: – automatic transmission (my wife insists on it) – economical – enough space for a foldable stroller and a medium-sized suitcase – price up to a maximum of 4000 € What can you recommend me ? Most of all my wife will use the car and that also only for shopping and everyday life (e.g. doctor, playground …). I think on average we will not exceed the 10000 km mark in the year. I thank you in advance for suggestions.
