For those who already have kids, what extra things will i need? I know its early, but trying to figure out what ill need. I have so much stuff and have kept everything from my son, I know ill need a double pram and think we are getting the nipper 360 I will need another car seat, although i may get two new ones and im thinking ill sleep them seprately, so another crib and sensor monitor. what else am i missing? i have two swings, i have a bouncey chair, a jumperoo, lots of mats etc.
