L will be 2 this week. She'll walk back from the duck pond which takes me half an hour pushing the buggy, but it's over an hour when she walks. We couldn't walk there and back
She was an early-ish walker (11 months) but is not a very physical child. Plus a lot of the places we can walk to, like nursery and town, tend to tire her out so it's not fair to expect her to walk both ways on top IYSWIM. It's not such an issue if you're just going out specifically "for a walk".
I'm also worried about managing a buggy with newborn plus a toddler on reins. It's tiring enough just managing empty buggy plus toddler, and I think it's bound to be harder with a baby in the pram. We've bought a 2nd hand double. It's for me rather than her.
Congratulations btw, I didn't know you were expecting again!
