Shite day. Won't go into details, but bloody sick of my babies being ill.
Evil when you have emotions for someone as strong as maternal love, it is normal for those emotions to swing pretty wildly when they piss us off. So yes, I think, getting angry with a six month old baby who just won't stop crying is natural. Of course it isn't the baby's fault, and it doesn't mean you love him any less or that you are a bad mother or whatever.
As long as it is fleeting, and not acted upon, Don't worry about it. I reckon pretty much all of us at some point have felt pretty damn pissed off with the screaming baby in our arms. Especially at stupid o'clock. When you llove someone as much as we love these little monsters you have to have the whole range of feelings from time to time. If we didn't let them get to us then that would make us indifferent.
Right. Ready for another night of listening to LO breathe, and cough, and splutter, and breathe, then pause, then breathe again suddenly and go into a coughing fit.... Fun fun.
