We have the same problem - everyone is right

- put a little Ice on Ice or Cowboy magic in the worst places - under the arms - behind the neck and sides - well - pretty much ALL over lol - and it'll help cut down on matts - also - don't let them wear clothes ALL day
and play - you'll find out the hard way what bad matts are - believe me - I did that when Cheri was a baby & it was a pretty bad mess.
