Is this a pushchair with a bucket seat I couldn't see ? My ds like the bjcm original 3 wheeler lwhich lies flat. We have an old 4yr old one but want to get a new one. Ds hates the uppa baby seat so it would need to lie flatish. Is this a stage he is just going through as now considering getting rid of the uppa baby as he screams in the seat and is too big now for the carrycot at 4 1/2 months old. Happy to use the old bjcm till the new one comes or buy a gt.
