No More Teeth

Okay, so teeth are obviously a popular topic for us. Just a recap: Shelby's bottom left tooth came thru on Thursday (she is 4.5 mos old). Trenton looses his bottom right tooth on Saturday, new tooth is already coming in. Sunday Shelby's bottom left tooth is barely coming thru. Did I mention she is 4.5 mos old?? Its great she is getting teeth, but I have been so successful with nursing her, where I wasn't with Trenton, I don't want to have to stop nursing her yet. Maybe they will take a long time to come up, wishful thinking, huh? I am willing to any advise on nursing a baby with teeth.
