I think it has to be your decision hun, have a chat with DH and discuss that you're not sure etc, maybe do a little research, I just wanted to give you my reasons behind why I didn't leave Libby, I'll find the text I used and let you know where it was from etc, as I was reading abook about it when I was deciding whether to leave her to cry or not......I definitely believe that they cannot be spoilt at Kenzo's age.
If you were asking this question in a year, then maybe you would need to leave him to cry sometimes, I still don't leave Libby to cry cry, only to whinge, as she is at an age where I know the difference between the different cries.....and she knows what happens....if she whinges, I can distract her out of it (without a cuddle) so I know she wasn't genuinely upset, just trying to get my attention

Then it is slightly easier to try to leave them to cry in their cot, because its also teaching them something positive which is that they can fall asleep alone and its OK.
