Pain of Pregnancy

Haven't been blogging for quite some time again... Recently just delivered my 2nd child.
It make me wonder how much pain a woman can go through for her kids... (not for all but at least for a few who really did went through it whole heartily for their children)

First the 10 months of heavy weight and discomfort that may be experienced throughout the pregnancy.

Second the Delivery pain that one can go through without much assistant except for the laughing gas and pain killer shot (not even epidural)

Third the breast engorgement and nipple pain that occurred on and off throughout the following 3 to 4months (esp. the first 2 months - for the 2nd one just the first 6 weeks, I experience 4 time of engorgement)

Fourth the lack of sleep for the following 4 to 6 months due to every 2-4 hourly feeding and expressing (plus the need to balance been taking care of my first kid).

Thank you so much that I have my mum's help throughout... else I think I cannot make it.
