My 6 week old buba is already too long for her pram carrycot! Weve got the cosatto Wow. The seat for it goes pretty much flat and the straps will go down small enough to fit her. Ive put an insert in to keep her head stable. The only bit Ive read about is the bucket bit could be an issue, do I need to worry about that or not really? I dont know what the actual reasoning is to why they shouldnt go in the seats even though they go flat?
