Skim read so apologies if repeating…. how big is your car? One consideration when going for a travel system consider how much space the seat and base take up in the back seat as some need the passenger seat further forward than others.
Also are you considering having two children reasonably close together? If so might be worth looking at a travel system that can be adapted to take two kids. Whilst by the time your second is born first one is likely to be very keen to walk you’ll need some way of restraining the eldest while you tend to the youngest.
We’ve just bought a Mountain buggy diet for our two – not used it yet but I’m impressed by the brand and the simplicity of it.
My personal experience says to get one with air in the tyres; we have a stroller too and whilst it’s handy in a shopping arcade the solid wheels are very poor on pavements.
Lastly if you go for a travel system get a roof box as when you go on holiday you will have chuff all space for the rest of the baby’s stuff let alone your own stuff.
Recommend a trip to a large mothercare or to Kiddicare (its a shame they closed most of their branches) and just try pushing them around and find one you like.
Congratulations though – being a dad beats anything else I’ve ever done in my life.
