Inlaws make me feel like shit for caring for my son

I absolutely love my mother and grandmother in law. They have been awesome. But lately they are really getting on my nerves. My baby is only a month old and is only breastfed, so he is very attached to me and he is still young and feeding A LOT. The in laws won’t stop making comments like I ruined him and I’ve spoiled him to much by not letting him cry it out. They get mad because I haven’t left him alone yet and he cried for me after they hold him for a half hour or so.. they tell him “oh you don’t need that tit yet” and try to keep him from me while he’s screaming. I don’t believe you can spoil a baby. When he cries for me I will take him and comfort him because that is what a mother does. I also will not deny him from eating because he “just did”. Babies that young eat often because their tummies don’t hold much. Ugh sorry for the rant. It’s just not right to feel guilty for “hogging” your baby.
