For #1 and #2 I didn't bother with a capsule. For #3 I have bought a capsule that goes up to 12 kg because before DD3 reaches 12 kg, DD1 will be going to preschool and I would rather let DD3 have the sleeps she needs. I also got the 2 strollers that it is compatible with (1 3 wheeler for DH to run with and one umbrella to stay in the car) so I know that I dont have to disturb her if I do need to go into the shops.
