You know you're tired when...
forget to put water in the microwave steriliser and melt all the bottles, teats and collars, not once but 3 times. LOL

You know you're tired when...
your DH turns up at the health centre to see if you are opk cos you left the front door wide open and went out (done that loads of time after no.2 was born too!)

You know you're tired when...
forget to make milk at all and don't wash bottles, and only realise at 6am when you have a screaming baby.
