Oh, I was just going to reply to you and here you've gone and erased it int the last half hour! Well, without having your post in front of me I am going to reply anyway. Basically, I was going to say that you just have to do what you are comfortable with in each and every moment and try not to feel pressured by your family, DH or even by yourself. If it feels bad to you, don't do it!
And personally I think you shouldn't second guess the sleep deprivation induced insights or questions either. I think that one side effect of being sleep deprived is that it can open up channels/sensitivities that we aren't necessarily so aware of normally.
I guess I should add the disclaimer that I think sleeping with my baby(ies) is the sweetest thing in the whole world. And that's even considering how much my first one kicked around the bed (and still does at almost 3 years). We got a lot of pressure not to do it, but we are still doing it and I think it has made our whole little nuclear family much closer as a result. But breathing my baby's milky breath is just such a precious experience, and it will be so short lived, even if it lasts a whole 2 years, that is still very short...But then again, you really have to do whatever feels right to you.
Sorry, you probably want to forget the whole topic and here I am posting on your thread!
