First time mum and looking for really simple advice around travel systems. I’m only 16 weeks so got plenty of time, but the more I read about them the more confused I feel. 
I keep reading conflicting things about travel systems that include a car seat that can attach to pram - is it useful or not? Are the car seats that come with travel systems good enough? I’ve read people saying they would buy the car seat separately. Do I need to be able to attach car seat to pram? When would you do this - if you’ve driven to shops and they’re asleep?
I’ll be a single parent, live in a first floor flat and will probably be using the car quite often. Can anyone help?
