Strange behavior from my two year

My son just turned two and has been seeing his father for almost a year now, he already has supervised visits at his brother's house. For the past couple months my son has came home asking me to kiss his "hinney"(bottom). At first I thought he was being funny, but then a couple weeks ago he started telling me to kiss his "boy parts." I understand boys are curious, but I don't and never have said anything like that to him and he mostly seemes to say it when I am changing his diaper or during his baths. I'm a single mom and my son is with me most of the time. The only time he is really away from me is during his father's visits, but I don't know who is around, I don't even think they are where they are suposed to be. Should I be worried about the comments or am I overreacting?

As a mom, if you feel something is off, listen to your instincts.  Ask some questions and find out what's going on.  If you think that this is something that has come up suddenly, find out.  Kids will usually repeat what they hear or see.  If you're not exhibiting this behavior, someone else might be.  Kids are curious about their bodies, that's normal, but they usually don't come up with things like that on their own.

I totally agree with marie on this.  I would be very concerned with what is going on when your son visits his dad at his brother's house.  He's had to get these particular ideas from someone.
