I agree with Fiona. In hindsight I wish we had paid the extra and gotten the capsule which comes out and clicks into the pram (we got a birth to 18kg seat). So much easier when they've fallen asleep in the car and you just know that they are going to wake up the minute you unbuckle them - particularly if it's been a stressful trip to the shops and they've finally gone to sleep!!

Plus, if you are keen to have kids close together you will need to get an extra carseat anyway once bubs number 1 outgrows the capsule and bubs number 2 is ready to go into it!
