My baby is 11 weeks old and has been using his pad since he was 8 weeks. I started out by putting him in a playpen with puppy pads in it every 30 mins. so he would get use to them. When he would go we would give him lots and lots of love tell him good boy make a big fuss about it. When he would go on the floor I would pick him up say no and put him in the play pen. Now I have a puppy pad on the floor in the kitchen and living room and he uses them He is about 99% puppy pad trained to poop and 100 % to pee. My little guy is a quick learner he sits and just today learned to shake it is to cute. Good Luck hope this helps. Congrats on your baby be ready to have your heart stolen. LOL
Hugs,
