Hi! I am a SAHM and just went through a similar situation. I have a 4 year old and a 15 month old.
My first was so easy because we had a structured environment. But, my son was a little different. I had no choice but to have him in the bed with us from the start due to the fact that we were either at parents house or in temporary lodging while my husband went through some training for 9 months. He would wake every 2-3 hours and like you the reason was the same....he wanted to nurse not for nutrition, but for comfort. My mother pointed out that my son's sense of smell is so keen especially for breast milk. So naturally when he rustles around and smells it he wants a taste and it also provides comfort. Kind of like adults are when they smell their favorite food or coffee:) I had never thought about it like that before.
To make a long story short as soon we arrived to Germany and got settled into our home I decided that as much as I loved having him close it was time to transition him to his crib (he was 10 months old). I started with naps when my husband was at work. At night, I still got up and went to his room for the first couple of weeks 4-6 times a night sometimes to breastfeed when patting and cuddling did not work, but I established the fact that he was returning to his crib and starting limiting when I breastfed. He finally started sleeping through the night after about a month and I can honestly say that both of us are more rested and happy in the morning.
I stopped breastfeedinig completely around 13 months and now we lay hime down after his bath, give him kisses, cut off the light, and he puts himself to sleep without a problem. It is wonderful:)
Just remember, each situation is different and you know what you and your son need. It will take a lot of effort, a lot of patience and unsterstanding, and most of all you making up your mind on what is best for the both of you. Talk to your husband and decide together....whatever you decide, stick to it and do not waiver. The worst thing is to have him in a crib one night, your bed the next, and so forth. He will get so confused.
