FTM here and curious..! I have a second hand Mothercare Orb. It didn't come with the apron cover (think that's what it's called) or a newborn insert/mattress. Are these necessary or do blankets suffice? I don't want baby to be uncomfortable and it seems like she would be as the pram currently is. New to all this so any advice will be much appreciated! If this would be better posted elsewhere let me know.
