Your son still has adjusting to do,and he is in the habit he used to sooth himself from the move.
Even so, there are a couple of things you have to do no matter what if you want him to sleep all night.
First, over-stuff him with food all day long. Babies often seem fine but don't eat to capacity during the day, causing them to wake up during the night. I learned this with my daughter who needed to wake up and eat a little at night until she was one year old. I fed her on a schedule, she was always satisfied, and I gave her a thickened bottle at night. To no avail, she always woke up twice per night and wanted food. My step sister (mother of 12) clued me in to the extra feeding all day long, and after three days, she never woke at night again. Babies will not over eat, so offer him food more often, and let him eat more. It takes a little while (few days, week) for the body to realize it's really full, but soon his belly will not wake him up at night.
Once you know he is full, then you should employ the CIO method. Comforting without feeding is just as bad, because he's still not learning to sooth himself to sleep. Remember, while he's crying, you're only doing this to enable him to feel comfortable and secure at night by himself. If you stick to your guns and feed him really full, he will sleep through the night. My one year old son has been sleeping like a stone through the night since 3 months with this advice. On the rare times he wakes at night and I have to go to him, afterwords, when I put him down, he rolls over and falls to sleep totally at peace to be left alone since it's all he knows. GOOD LUCK!!!
