Double pram or single pram + buggy board

I had a baby in April and we opted for a buggy board. He hasn't been a big fan of his pram for a while but also isn't ready to walk everywhere (plus he tends to run off at times) so we also got a stroller for when the four of us have a bigger day out. We couldn't have fit a side by side buggy in our house and a lot of the others had a weight limit of 15 kg for the toddler big and he's too heavy already x

I would get a cheap double, side by side. The ones that go in front and behind I notice the older kid being too tall to sit in it. I have a 2.5 yr old and an almost 5 yr old and my older one still will occasionally use it if we have somewhere to go and there’s a lot of walking. I got one on amazon that was like $150. If you go to a lot of places with your kids it’ll be useful. But also I try to make my older kid walk as much as he can bc he’s getting older, but he still does say he gets tired.

I have a Joie estrella for my son and newborn the seats go up to 22kg so could get long use out of it. We also have a buggy board but my son likes to jump off and run away at times so we only use it short walks like to the park etc x
