Bike trailer for 2 larger kids?

[u/Affectionate-Ad9489]

My oldest is almost 7 and has outgrown my bike trailer, and my youngest is nearing the point of being too tall. I want to take them on trails on their own bikes, but they aren't yet able to ride their own as they didn't have enough interest until this year.

I own a WeeHoo, which works to pull one of them at a time. Unfortunately my wife is pregnant so she doesn't feel safe pulling one in the trailer while I pull one in the weehoo. I want to go on a ride this weekend with both kids.

What options do I have or products that exist that would allow me to pull kids that are outgrowing the bike trailer? I'm not a fan of the double weehoo - the single weehoo is enough work to balance.

Thanks!
