If you cannot put your baby to sleep without nursing him, you may want to try a few things. You may want to try nursing the baby and then putting the child to sleep before he is actually asleep on you. Also, it is okay if that is the way you want to do things. Always remember that it is up to you. The habits that you create now are going to be the habits through the baby´s young years. If it is okay with you and it doesn´t bother you to do it now, that is fine. But think ahead. If I do this every night with the baby, in six months from now am I going to want to continue it? If the answer is now, then you need to find another solution. If the answer is yes, I don´t mind, then it is okay. If the answer is no, try things such as feed the baby, make sure the baby is awake while feeding, then burp the child, then lay the child down so that they get a clear distinction between when it is time to feed and when it is time to rest. That is my advice to you.
