I have 2 10 month twins and a baby in the way. The twins will be into the next stage up by time baby arrives! I have a land rover discovery sport and want all 3 in the back, has anyone had any success doing this? I have 2 britax first class which I was told by pram centre fitted and we tried it out, it was a tight squeeze but doable, when I went to mother care they fitted them and said not safe as touching and when you put baby carrier into Isofix vase it pushes against the 2 others seats! I'm so stressed trying to find good solid advice
