I put the tshirts on her, as we only have 2 tiny ones that fit, but its because we have already had to start using our air conditioner in las vegas, and i do not want her to get a chill, but we have the vents closed where she sleeps, so she dosent wear them when she is in her play pen..at first she wouldnt even get up in them, but she soon realized the only way to follow me was to walk in the tshirt, took about 2 hours, now she sits to get them on..
