if you can teach hayden to self settle ASAP it will pay off later. My son slept throug at 6 weeks and learnt to self settle. It can be tough to teach but pays off. I also did not put a dummy in his mouth each time he woke in the night as this meant that he would expect it and so one would be getting up frequently in the night to put dummy in mouth which i rerad other mums are now strugglying with. My son will go to be with a dummy More often then not but nos once its out, thats it.
Perservence is the best recomendation.
