because of the security I gave him by meeting his needs.
Good for you, this is exactly what it is all about!

I have another success story here.

Co-sleeping and feeding to sleep successfully, now with a two year old who happily sleeps in her big bed.

I did not always feed to sleep, but just didn't get stressed if that was what happened.

I did find that at about 6 months - 8 months, the co-sleeping stopped working as well for us as DD was looking for the breast all night and was not settling properly as she just wanted to constantly feed. I was not getting any sleep so we then started her sleeping in her cot. I think that it is all about reading the signs and going with them. I will definitely be co-sleeping with my next one too - provided he/she wants to .

I think it is all about meeting needs and creating a happy self confident baby/child whatever your method. You sound as if you have it all worked out well!
