It's only a sleep problem if its causing problems for you or your baby. If he's happy and you're happy then leave things how they are. You can always change things later on if you need to. Of course if you want to make changes there is so much advice out there, you probably just need to pick an approach that you think will work for you and give it a try for a week or two. I tried SOS with my DD but it didn't really suits us either.
There is no need to change things just because other people think you should!
