I wouldn't say I've had it hurt yet, but I've definitely had the kicking the nerve moments! I almost jump out of the bed! I'm finding myself telling bubby to go to sleep already LOL. (I'll give him credit tho, he kicks late at night, then seems to sleep through till about 5.30/6.00. Maybe daddy's story before bed everynight helps him sleep?) Most of the kicks are out to my right side and very visible. Some even make my whole belly wobble, quite amusing really. Not looking forward to the painful kicks tho!
