Every time she eats or drinks anything and whenever you see her sniffing around pick her up and put her on the pad. Once she puts her scent on the pad she will usually return to it. This worked well for Sophie until she wanted to chew and play with the pad. At that point we started her outside potty training and now she is housebroken and very, very rarely will have an acident in the house. Congratulations on your new little one.
