What do you think about posting naked pictures of your baby online? Please help?

Okay so i have facebook to share pictures of my family, with my extended family and friends, only my facebook friends can access my pictures.. Well I have 2 pictures of my 5 month old daughter naked, she is sitting up, you can not see her private part but you can see her chest..I thought it was fine but one friend messaged me like, "why would you do that, there could be child molesters that hack into your page and see her".. So what do you think? I thought it was fine since you can not see her girl part what-so-ever. Please help!
