Potty training 20 month old

Samantha

My son is 20 months old almost 21 months and he is showing all the signs of a toddler who is very interested in potty training. So my husband and I went out and bought him his own potty and training pull ups today. Any tips or advice anyone can give us? We have a 7 year daughter so it was a little easier with her when we potty trained her.
