Breastfeeding help

Kelly
Had my boy 6/6/16 at 6.34am he has been breastfeeding since been born. But today he has literally wanted to feed all afternoon everytime I put him down he screams until he gets back on my boob. Not sure if he is just been a pig or using it for comfort. I can hear him taking milk so I know he is getting it. Debating giving him a dummy just so I can get a few minutes without him on me
