Honestly in my opinion i think it depends on the child. DS1 self settled from about the 6 month mark and sleep was a beautiful calm place for him. DS2 did too, he was a bit more difficult at times but being in our arms to go to sleep was way too stimulating for him and he hated it. THEN DD came along... I have learnt that there is no way you can make her do something if she doesn't want to (took me 18 months) and i'm already runing scared for what i have ahead of me, neither of us like to give in I fed her to sleep, rocked her to sleep and as much as i loved to do it i also got very frustrated in doing it and it got to the point where it was getting harder and harder to get her to sleep. Would i change any of it?? Probably not, it worked at the time. I made changes when i felt it was needed and she has adapted really well.

My honest opinion is you need to see what it is your DS wants to do. Sounds like things are going really well at the moment so as most have said why make any changes when you are happy with the way things are. If later on you feel you want a change the option is there, he just may take to more than your DD did.

Good luck and most of all enjoy your little man
