We used the little tummies drops, which have no added sugar or artificial flavoring, those really seemed to help a lot. and we spent a lot of time taking turns sleeping with him on the couch or in a recliner with him on is tummy on our chests, he was a lot happier when he was on one of us and on his tummy.
We weren't worried about following the 'back to sleep' recommendation because research I looked up when pregnant showed that there was in reality no statistical difference between SIDS cases since the back to sleep program started and before. Because when you group all the causes together [unconfirmed/SIDS, strangulation, suffocation, asphyxiation] the percent is still the same since back to sleep started as it was prior. The reason it looks like there was a decrease is because now more infant deaths are being recorded as suffocation, strangulation and asphyxiation and less as SIDS/unknown. so the percent of unknown has went down and the others have went up (so this is more to do with medical practice getting better at figuring out causes basically). So, when you look at just unknown/SIDS it makes it look like back to sleep is affective. However, when you look at all of them you see that nothing has changed. Plus the research I saw showed that co sleeping is one of the factors (along with breastfeeding and baby wearing) that statistically seems to reduce the risk of SIDS. Which made me even less worried about him sleeping on us.
He also seemed a lot happier in general if we wore him in slings or in carriers pressed against our chests (he liked the carriers better then slings, I think because of having his tummy up against us), and on the worse occasions we would just walk around with him laying flat on our forarms, so again the on the tummy thing really helped.
Other then that just time, I know it's rough but you'll get through it. ~hugs~
