A.O.
This is very much a personal choice, I come from the thinking that when a baby cries they are crying for a reason and it deserves tending to. I know that when I am hungry I get up and eat, unfortunately they have tinier tummies and lack the capability to get up and feed themselves, I fed my sons as often as they chose to be fed and eventually they no longer needed to eat at night. I had decided that I was not going to try and teach my kids how I wanted them to behave for me as infants rather than what is it I can do to make you comfortable. that's not to say I do not provide structure and discipline for them now but as a baby with such little understanding of the world around them and inability to get a point across with words or comprehend why they are feeling one way I just tended to them. the theory being you can not spoil a baby. Like I said each parenting style is unique and you have to do what you heart tells you is right, know that whatever you choose, if you are trying your best and have that Childs best interest in mind that everything will work out. good luck!
