cosy-ing up BJCM and ABC Everest double (and triple!) buggies for nb twins?

[DreamingOfPeace]

Hi,
I have a 16 month old and expecting twins in April.

I have a baby jogger city mini double plus the ABC everest triple. Both second hand. The BJCM is a 2011 model though.

I don't want to buy carrycots due to the expense plus couldn't use on the ABC.

Was thinking sheepskin liners? (Loads online, which are any good?)
Some kind of liner?
Phil and teds cocoon?
Other soft cocoon?

Help please!! Ideally that I can use on both buggies.

Any soft cocoon will work if you just attach it to the D rings on the seat units. I'd probably use cocoons personally, then just normal liners when it's warmer.

I would buy Bugaboo cocoons. They will be easy to swap between the two as there's slits at the rear for the harnesses. The babies will be strapped in which is always good. They should last you around a year, so although expensive will last. There's nice head support. They have a good resale value later.
