So I am going to get the Land's End bunting for my 16-month-old (don't feel like messing with dressing/undressing/redressing or trust others to do the coat trick), and I wondered if anyone knows if their stuff tends to run big or small or neither. DS is 24.5 lbs, so the 18-month size *should* fit (goes up to 26 lbs), but I know the weight- and height-based sizing is often off (Children's PLace always runs big for us). Anyone have experience with Land's End sizing? We have a ped appointment tomorrow, so I'll see how long he is and factor that into the size too. Would it be a bad thing safety-wise if I got him one that is just a little too big? I only want to buy one, and it will have to last from Nov through March. TIA!
