Hi I have bought the Phil and teds double fir a 21 month old and newborn I have the newborn caccoon thing so new baby can lie flat under the toddler. I was so happy with it then read a comment from a woman online who said it tips if the toddler gets out! Surely this can't be true I've emailed them and they initially said it can be used as a double or a single and then when I said is the newborn ok in it if the toddler decides to get out and they sent a standard reply but I now feel s bit nervous. Has anyone got this pram and can U reassure me? I've bought the sport version. Thanks
