Am I a bad mum?

I have an almost 2 year old and a new born. I'm a single mum and I rarely get to sleep.

In the mornings when my son gets up if its been a particularly bad night I shut all the necessary stair gates so he has only access to my room to come get me if he needs anything, his room and the living room. Get him his juice and breakfast and after he's eaten I'll put his telly shows on and go back to bed for a hour or two.

I recently told somebody this and got told im an awful mum.. but I don't think I am. Hes got nothing in the rooms that could harm him, nothing he could choke on or fall off, I just see it as doing what I need to do to be able to look after both of my children.
