Pushchair for tall toddler and maybe a new baby

[Broombroomwitch]

I’ve got a 2 year old who has outgrown the pram I currently have. She’s only 13.5kg and it’s supposed to go to 22kg but she seems to be far too tall for it.
At the moment I just use it a couple of times a week so I can go for a walk to get some exercise. I was going to just give up on this because I didn’t want to invest in a new pram, given she’s probably not going to want to be in it much soon, but actually it’s the only time I get to do any sort of exercise so I’d really like to continue if I can.
For a while I did decide to just let her sit in the too small pram for the sake of just a few walks but now I’m Ttc and will need a new pram anyway.
So I’m wondering if I should either
a) keep this pram for now even though her head is pushing through the hood.
B) buy a new pram and then maybe buy a double pram in a few months if I get pregnant
or c) buy a pram that works for my toddler now, and will do for either the toddler or the baby interchangeably in the future. And I can baby wear when the toddlers in it and the toddler can walk when the baby is in it (is this realistic?!)

any advice on which option you’d pick and what pram you’d buy?

TLDR
should I buy a single pram that I can use interchangeably for a toddler and a new born. And if so do you have suggestions for which pram to get

Look on Facebook marketplace - uppa baby Cruz is a good one lasted my tall son until over three and can get a buggy board for it when baby is here

Thank you I hadn’t looked at this one yet.

can any mums of (almost) 3 year olds with a new born tell me if a double pram is worth it or if I can get buy with a single one?

Do you have a budget? I have a 2 year old and am currently pregnant, I’m considering ordering a bugaboo donkey for the fact it’s a side by side double but can also be used as a single

Not really, obviously I’d like to spend as little as possible though for what I need. My first dc wouldn’t go in the pram for first 18m so i was pretty happy I’d not bought a really expensive one. Now it’s covered in food and muddy footprints and I’m still glad, but will spend whatever I need to

You can definitely get by without a double. My second was born when the eldest was just 3 and he’s been walking ever since.

Mine can walk but it’s very slow, I like to get out for a walk for my own exercise (sahm, very little childcare and dh that works long hours, so it’s one of my only options) so it’s better if they’re in a carrier or pram for that, it’s the only thing we use the pram for and I’m reluctant to start going at toddler pace
but I know they’re going to outgrow being in the pram at all at some point anyway
