We go with the self soothing method. Both of our kids were sleeping through the night from about 2-1/2 months old till they were about 10 or 11 months old. They then realized that they could wake Mommy and Daddy up if they were persistent, until Mommy and Daddy got smart. We used a method where, when they woke up and started screaming, we immediately went up and calmed them down for 2 minutes, however, we didn't make eye contact, and we didn't talk to them. Just patted them on the back and made shushing sounds. Then we would leave for 5 minutes. If they were still screaming after 5 minutes we would go back in and calm for 2 more minutes. Next time we would leave for 10 minutes. They would almost always have put themselves back to sleep after the 10 minutes but if they didn't, we kept adding 5 minutes to the time. They learned to put themselves back to sleep and still, occasionally they'll wake up but it is a rarity. The other thing is that from day one we refrained from using "sleep aids" to put them to bed, i.e. mobiles, music, etc.. Lastly, when we put them to bed, we read for 15 or 20 minutes a night and then put them in the bed whether they're asleep or not. That also teaches them to put themselves to sleep. It probably all seems very regimented and rigid but I will say that we're one of about 10 families that we know of that have kids that sleep well. I have a good friend with a 14 month old who has been sleeping in his bed since she was born. In fact they bought a king size bed to accomodate her. ABSOLUTELY NUCKING FUTS.
