Hi Eliza..I can understand your worries about having a 2nd baby after a harrowing 1st c-sect..For me,my eldest son was born on Nov 2009 via emergency c-sect..My 2nd son born on May 2011 via scheduled c-sect..Now i am currently almost 20weeks pregnant with my girl..
Weirdly enuff my recovery for my 2nd c-sect was a bit faster than my 1st c-sect..But you have to take extra care of your wound..Try not to carry your eldest son after your operation..For me i took care of both my boys all by myself 2 weeks after my c-sect as both my in-laws are working..
You must keep your wound area clean..and check for any pus or smelly discharge..For me i took this sea cucumber jelly..It helps to "clean" the wound internally..It also helps if you can get sum1 to make the fresh black fish soup..
Dealing with a 2nd c-sect while attending to my newborn and 18mth old son can be overwhelming sometimes but you need all the help you can get so be open to offers to help you take care of your elder son..!!!
If you take all these extra care after your 2nd c-sect then God-willing,im sure you will be able to recover and not have another harrowing experience..And since you mentioned your son is already 3yrs old,then its good to have another baby now so that their age gap wont be so far out..Wen they grow a bit older,you will see them happily playing with each other..You will think that all your pain of going thru multiple c-sects will be WORTH IT..!!! Have faith my dear..!!
