@Gigitree I think your right, I think there must be something theyre born with that makes them better sleepers. I know loads of people who have more than one children and one was a great sleeper and the other a terrible one! They say you dont have two babies the same - but I dont think I will be testing that theory! 
@magpie21 Tbh I probably simplified it and it's not as good as it sounds! - its quite hit and miss and often a battle to get him to nap. He doesnt sleep in the pram or car seat anymore and has never been comfortable sleeping on me so I dont really have a choice but to persevere with putting him in his sleepyhead and letting him get on with it! Haha
He woke up every 2 hrs last night - hello sleep regression!! Hoping that the ladies who are a few weeks ahead can soon tell us how the regression ended and give us hope...my wonder weeks app says 27 days remaining - argh god help me!!
