I have bought the britax b agile 4. I will be using it mainly with carrycot or the car seat for the first six months. The problem is with the carrycot it is such a tight squeeze(and I am 5ft tall) that I needed to take the seat fabric off as in fact the instructions suggest. This makes a lot of sense as for first 6 months will be using carrycot and car seat interchangeably so just slotting them into the adapters. However after taking the car seat or carrycot off the chassis, without the main seat fabric I can't fold the chassis. So frustrating! Any suggestions of what I am doing wrong?
