Does your son put his hand down your shirt, too?
My 18 mo old son is doing this constantly since I weened him from breast feeding. I only stop just a couple of months ago, and now whenever he's near me, tired, or upset, he puts his little hand down my shirt and holds my you-know-what. When I talk with other women about this issue, surprisingly their sons have done or are doing the same thing. I guess this is common?
