is a bassinet stroller necessary? (for Nuna Triv)

Hi all,

I just purchased the Nuna Triv travel system and I'm wondering if I should buy the bassinet that attaches. I walk A LOT and this will be a July baby so I think I'll get lots of use out of it. Please let me know your experiences and if you think it's worth it.

Also - I purchased the Newton Baby bassinet for overnight sleep because I am TERRIFIED of suffocation, so this would be purely for walks and if we visit friends.
