When I got pregnant for the first time, I was naturally very excited and immediately bought the requisite What to expect... series. Pored over it, surfed countless websites, subscribed to Baby Center, you name it.
And since we lived near my mom and grandmother and my great aunt who raised me and my three siblings from babies, I had a wealth of advice that was immediately accessible (whether I wanted it or not), twenty four by seven. Not all of the advice is based on scientific fact by the way. Examples of which are:
Superstitious belief #1: Never bring the baby out of the house until it's been baptized. Not sure if it makes the baby susceptible to possession of evil spirits or something. No one ever comes out with a reasonable explanation. Just a vehement "Basta!" (tagalog word for "just take my word for it, you ignorant fool"). Ok, take out the ignorant fool part, I was just kidding about that.
Superstitious belief #2: People visiting the house and seeing the baby must dab the baby with a little bit of their saliva (I know, altogether now, "EWWWWWWWW!!!"). This is to prevent "usog" which makes the baby cry non-stop in the wee hours of the morning. The dabbing must be done on either the foot, the stomach, or the forehead.
Superstitious belief #3: Filipinos have a healthy respect and belief in elemental spirits. Which is why, whenever my sisters and I came in from playing outdoors with unexplained bruises on our legs, my grandmother or aunt would say, "kinurot ka ng ingkong" (you've been pinched by an old elemental spirit cause you're cute). Ha ha, just added that last part. This has been so ingrained in me that when my kids play outside, I have to bite my tongue before I blurt out "tabi po, ingkong" (please stand aside).
Imagine what my very un-superstitious hubby has to put up with in our household. After he had to grapple with superstitious beliefs for newlyweds which makes me chuckle everytime I remember those days (and which can take a whole new post altogether).
They mean well, they really do. And I love them for it. It's something I can laugh about with my sisters and hubby. But I guess the point is, there are a lot of instructions and advice out there and for a new mom, it can be quite overwhelming.
I would say just go with what feels right for you and your baby. Because I find that what works with one baby doesn't necessarily work for the second one. And most of the time, what's practical works best.
