Not necessarily but I don't drive and the town is a bit of a walk for him so wanted something to last past him being 3 that we can take with us to the shops to put shopping in and that he can use if he gets tired or needs a a sit down. The pushchair I have will do up to 3 years so if I'm gona trade it for a stroller I want something to last if needed but the pushchair is top bulky and heavy and hard to control one handed if he's walking so I do need to trade it for something more suitable
Ah I see. We did put ours in a backpack carrier thing when he got really knackered. Hope you get a good answer.
My eldest was pretty happy to walk everywhere once he hit 3.5-4. Is there a particular need for a stroller for when your LO is 4?
