Going to travel with baby in a month....

Ta

And I have no idea what I can cannot bring on the plane for him. I have looked on the website and that didn’t really give me much to go off of. I guess I’m basically freaking out about car seat and stroller and I guess if I’m allowed to bring his formula (which I’m sure I can) but don’t know if there’s a limit on how much I can carry on. I pretty much need to know about everything when it comes to what I can bring for baby.
