Why 5!!!???

Why 5!? Why not 6 or even better 6:30! But no it's always around 5 fecking o'clock that my small bundle of joy wakes up and makes too much noise! But wait it's not only at 5, but also 2 and alittle earlier 11!!
He's 7 months an 2 weeks old, surely he knows by now that mummy and daddy like to have a wee bit of a sleep in! He was so good before going to sleep at around 7:30 waking up at 6 and that was that for a few months, then all of a sudden everything has gone up the whop. And don't give me this teething business, it's not like he has been teething for the last 2 months!!!! Sometimes even though I love the little bugger, I wish I could palm him off to someone else!!!
Right now I hav to go and rescue him from whatever he has gotten himself into and can't get out of!
