I was also like that for my #1. Discharged from hospital and found my feet swollen like an elephant. So i went back to see my gynae and she said its normal.
actually... after i delivered, i am swollen the whole body. during confinement, ur mother or CL will let u drink longan water.. it helps to flush out the 'wind' and water retention. it helps for me. in a few days time, the swollen will go away
