By the way, Potatoes, for your information only. Last time when I was once a first time mother, I know your worries. Baby eat alot, scare baby eat too much. Baby eat little, scare baby not enough nutrients. Baby no poo, scare constipation. Baby poo alot, scare diarrhea.
That's what mothers go thru. I am still going through this stage even though my number 2 is almost 1yo, cos I can tell you that irregardless of how long you are a mother, mothers tend too worry too much.
That is why I suggest you take note of all those breastfeeding support group and in my opinion, the all so important number of the kkh's Ask-a-nurse.
To tell you the truth, I find advise from KKH's ask a nurse much better than the PD or a GP.
I asked them practically about everything from my body, to my children and baby. Even when baby is having fever, I asked them when I should start bring baby in to check etc. As you contact more and more, you'll learn from the information you get that sometimes, your own gut feelings is the best indication. Don't listen to what other people say if you are easily swayed by them. Listen to yourself and TRUST yourself.
This are my lessons learnt from my 3yrs of motherhood. You can entertain other's advise (can tell you, it is non stop advise from day 1 to day infinity) but still not following them.
If they criticize you about it, just inform them you are your baby's mother and you have your own best interest for the baby too, only that it is not the same as theirs. I learnt mine the hard way when my elder child suffered a lot just because I listened to EVERYONE's advise.
