I'm 17 weeks with my first when do I need to begin thinking about all this pram and car seat and crib stuff, when I try to comprehend it my brain is like a monkey playing the cymbals at the moment
I found it all super overwhelming. Literally had a small cry in a Baby Megastore place when I couldn’t get a single pram/travel system to fold or come apart and couldn’t drop down the side of any of the ‘next to the bed’ cribs and I went into full ‘I can’t possibly be a parent’ mode. Then I remembered I was wearing big girl pants and we got a sales assistant to show us a specific system then asked to see any others that met our requirements which she did, then we went back around and tested them all by ourselves and I felt like I could actually do this. No criticism of the shop, we had decided to walk round the whole thing first and then ask for demos. They were helpful and completely not pushy about buying in the slightest. We did go to Mamas and Papas as well on the same day, but that point i was hot, tired and emotional and I’d been having crampy pains all day and I was just furious at the entire world and tried to wrestle with a car seat and failed but again, the woman in the shop was great, really helpful, helped me understand that the car seat and base I wanted did the thing I want it to do (swivel both ways and slide out to help my back and the fact that we sometimes park facing one way, sometimes another and I don’t want to get the boy out the car in the middle of the road). Again, she was zero pressure. She talked about buying appointments and getting some money off and about price matching but she wasn’t pushy about it.
I first went at 21 weeks pregnant. Probably had the smallest bump of all the shoppers but it was a 3ish hour round trip and we have had to plan our weekends with military precision lately to get everything done!
We knew we wanted an all terrain system because of where we live. We have accepted its heavy as a trade off, and that if we want to go on holiday we’ll need to buy some wee foldy lightweight thing, but I doubt we can even afford a drive down the street anyway

the ‘city’ stuff is definitely more nimble and light, but depends on where you live and what sort of stuff you tend to do really!
