Does your baby cry uncontrollably when getting a vaccination shot at the doctor's office? Turns out it's not merely a melodramatic meltdown. Researchers at the University College London have discovered that a baby's brain actually registers pain during vaccination shots, reports ScienceDaily.

A small sample size of 15 babies (1 month to 12 months) were studied. Each baby was given an EEG test, where harmless electrodes were placed on the scalp to measure brain activity, and also recorded on film while being given routine vaccinations.

Scientists then compared how each baby's brain reacted to the shots to their physical pain responses, such as crying, distorted facial expressions, and movement.

All babies experienced pain, but results indicated that younger babies (1- to 2-month-olds) had higher "spikes" in brain activities upon skin contact with needles, versus 12-month-olds. The younger babies' pain was given a rating system of 8 out of 10.

This initial research provides evidence that more pain-free vaccination (like the rotavirus vaccine, which is given orally) should be created in the near-future to provide better care for babies and also make doctor's visits less stressful for everyone.

Quick tip for all you parents all out there: My baby never slept well (especially through the night) until I started using the website >>>>SleepBaby .org<<<< - that website has been by far one of the best things I've ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! Sorry, you can't post links here so you'll have to turn it into a normal link. >>SleepBaby .org<< Best of luck to you and your family! :)
