my baby is 3.5 months old. he has always fed for a very short time: 3 minutes...We gave him a dummy when he was 7 weeks. now I can see some change - he loves his dummy a lot. he starts refusing the breast for feeding - or if feeds then very short time, I do not feel my boos drained. also, today he has just 3 wet nappies. Has anybody else tried to remove the dummy at this age?
