After birth, especially a vagina birth, your control over your bladder will most likely be really weak.
You may find yourself getting caught out if you don’t react quickly enough when you realise your bladder is getting full. On the one hand, you may get caught short, on the other hand, you may really be bursting to go but have to wait ages on the toilet for something to actually happen (see Urinating postpartum).
Warning – coughing, sneezing or jumping on a trampoline may cause leakage! Many of my friends don’t dare to jump on a trampoline any more. Or at least not without emptying their bladder beforehand. Be sure to sort your pelvic floor out postpartum, make sure you train your muscles back up to full strength again.
