Ladies I have a question !! My son is 6 months old and getting 4 teeth at once 2 top and 2 bottom yesterday he spiked a fever of 102 I took him to doctor they couldn't find anything but they told me it doesn't get that high from teething ! Did that happen to anyone else ? Now today it's only been 100.4 the highest ??!? Do u ladies think he's teething or what ?
