6 - Six Months Baby Development

Developmental Milestones You Might See

Has your baby started teething yet? There's no set timeline for when a baby starts to teeth nor is there a set time on how long or how painful the process is. This is very different for every baby, and parents need to pay extra attention. You might sometimes see a lump in the gum for a few weeks before the tooth cuts through, and there are other times, when it seems to magically show up overnight! Different babies will show different symptoms of teething.

Certainly the uniqueness of each baby and how they teeth was very apparent with our own children. With our daughter, her teething process seemed to not bother her at all, but for our son, it's a different story. For quite a few times just before a new tooth cut through, he would get feverish for 2 to 3 days! Sometimes, it would be a high fever as well. We were quite worried the first time, and made a quick trip to the emergency room! A few days later after the fever went away, we could see his new tooth. This feverish symptom happened many times during our son's teething process, and we learned to deal effectively with it as well - and no more panic trips to the emergency room either. One common symptom is that both of our babies drooled heavily, and would try to chomp on anything they can wrap their gums around. =)
