My confinement period is going to end soon. After that, when I resume back to my normal diet, is there anything I need to take note off like what can't eat or what can't drink as I am breastfeeding?

There is basically nothing you can't eat or drink. You can have anything you want but all in moderation. For example, many thinks that caffine in coffee isn't good for babies but I have been drinking since pregnancy till now that my gal is 8 years old, everything seemed ok. She even top her class. Lol However, do note what you eat in case baby has any allergic reactions to the food you eat which is from your breast milk.
