You need to do what makes you happy. Don't worry about outside opinions or remarks. If you want to keep doing it then do so, I don't know of any 5 year olds that still do it IFKWIM, but if you are not happy doing it (after taking away outside pressures), then there are some hard yards to do before it gets easier, its not really a bf issue its a sleep issue, and again it depends on what you are comfortable doing to sort it out. Its only a problem if you consider it one, not if society does.
