Breastfeeding your baby to sleep

Richelle
I'm definitely guilty...
My 10wo and I enjoy these cuddles we have right before I lay him to sleep. Granted he almost always wakes soon after being laid down, but he never crys. He simply gets to a comfortable spot and then falls to sleep. It's like our thing. His daddy has put him to sleep having bottle fed then laid him down, he doesn't go to sleep as quickly but it works. 
I read that this is bad, but for his naps I do not do it, just bedtime. 
I'm I creating a horrible habit that I'll one day regret?
