letting your baby cry..

I have a 2 month old and I love to cuddle with him and let him sleep on my chest, I know one day he will no longer want to cuddle and I want to enjoy being close to him while I can. But why do so many women insist on just letting your baby cry? And say that I hold him to much? I don't hold him 24/7 but I don't just let him scream just because "he just wants attention" why is it so wrong of a mother to give her child attention when they want it? Why show your child there not that big of a priority to you that you wanting to just want tv or something is more important then showing a child love? I honestly don't believe you can show your child "too much love" that's just silly
