Molars can take a long time, and they do come through differently. With our LO, we saw one point, then another on the outside, then the other 2 points, and then the whole thing moved up slowly through the gum. Ouch! For our LO, all 4 came at once, but it took 2-3 months for them to come all the way in. He definitely did early wakings during that teething process, but pain meds helped.
Now we're on early wakings from the 2-1 transition coupled with a cold. And JoC, I'm dreading the time change with you!
