How long does this last????

When my son was born I signed up for Pampers email. They would send coupons, tell me about up and coming products and articles about children that were the same age as my son. For instance when he was 6 months old I got an email stating "your son is now 6 months old, here are things he may be doing, interested in or what to watch out for". Today I got an email from Pampers stating "your son is now 40 months old". I'm curious how long I will continue to receive these emails. Am I going to still receive emails when he is 20 stating "your son is now 240 months old, he may be interested in sex, girls and alcohol so watch out".
