Wondering if anyone has any suggestions or has a 2 year old going through the same thing!?

My 2 year old wakes up every single morning at 5.30am..... sometimes I bring him back to bed with me and he may sleep for another 3/4 of an hour but usually thats it, he's up, and subsequently so am I.....

He's always been an early riser but for the last couple of months 5.30 seems to be the norm.... I am 4 months pregnant and usually have to get up around 3 to go to the loo and by the time 5.30 comes around I am exhausted and don't feel like getting out of bed....

My hubby works away, 2 weeks on 2 weeks off so Its just me, so I have to get up... no sleep ins...

Does anyone have any suggestions to help him sleep in to a more sociable hour?

Thanks
