What about all this scheduling babies..baby wise...forcing your infant into a routine stuff. So many people are for waking your baby up every 3 hours..never feeding them until the 3 hour mark even if they are screaming with hunger. I think this is very detrimental. Many doctors and nurses still teach to be waking your baby up on a schedule. What do you think.

Also what about Dummies / Pacifiers?

They help mums miss the feeding "cues"

There are many activities that aren't researched. Major issue is to consider what is the intervention and what is the "norm". For example, some research examines keeping mother and baby together immediately after birth, rooming-in as an intervention and separation as the control or norm.
I have a list of projects if students or others are looking for ideas. I can add others that you suggest www.bestservices.ie
Intervention trials are considered better quality evidence than observational studies. It is very difficult (ethics) to do a trial that allocates one group to pacifiers (or whatever) and one group not to have them.

I thought the whole URL would appear. After www.bestservices.ie go to Education, then Research and scroll to very end of the page for the link to the pdf of research topics.
