Does anyone have the sit n stand double stroller?? I have one for my 6week old and almost 2 year old. But my question is what infant car seat do y’all use?! I got the Graco Snugride because it said it would be compatible. It fits but I feel like my baby is leaning back too far? And I can’t find any videos online for the stroller, only vague instructions that came with it. Help Please!!!
