Noni -- how full on! It terrible that you aren't sleeping!!! I hear ya about how they don't realise how much work is really involved in raising a child. It is much much more than physical -- it is emotionally and intellectually draining as well. I would love to see him do it! haha
You totally deserve the vent and really should explain to him that while he is around on the weekend, you realise that he is also tired but you really need the break and assistance. I hope that he understands. It is really hard work and you are doing a great job. If it were me, my vent would have been much much harsher longer and ruder than yours! So you are a super hero as far as I am concerned!
Please take care. xx
