I enjoyed co-sleeping with our second baby, but for us it made the waking more frequent, and he decided he only wanted to sleep while latched on too, which was impossible. If it works for you, then it's a great way to live comfortably with a small baby who needs to feed in the night several times. What worked for us once I gave up on co-sleeping and put our baby in his own bed was a sleep training method called gradual retreat which took a month to do and was hard work but gradually helped him learn how to go to sleep on his own so that when he came into a light sleep he would settle again. Can dig up an old post if useful. It is a phase, try not to see it as regression as it stems from your baby developing into a new stage of awareness and maturity of a sort. I think all babies go through it. For what it's worth, I used to feel terribly guilty (with my first baby) when people advised 'it goes so fast' and 'you'll look back and miss this stage'. I would wonder how I could be so miserable and feel some days went so slowly when more experienced mothers were warning me that the time was passing so quickly and that I'd wish the newborn phase back. Clearly lots of people do, but I never have and find the older baby stage (and the toddler stage and the preschool stage) much more rewarding. Just offering a different perspective.
