Baths are ok. They are really good for your stitches actually, just add a little bit of salt to the water, and it will make them heal faster!
I agree with the above post, i would wait until say your 6 week check up, ask your doctor about swimming. I wouldnt go swimming, as you will probably still be bleeding by then, and you arent allowed to use tampons, but just ask your GP at your check up!!!
Congrats on your bubba!!! =)
