You're not sick, don't worry. Although it's been months since you have posted this, and your gf is probably way past her labor days...
Just wanted to let you know (for future reference) (and incase you concieve another bundle of joy any time soon)... You can always massage a pregnant belly to get her relaxed. Mostly clockwise in the direction of how the body digests the food (while she's laying comfortably "sideline". You can also massage her lower back and shoulders which is a big deal for pregnant women! They love it! But there is one thing to keep in mind... Be very careful when massaging her feet. There is few spots (reflex areas) that can interfere with the baby's development... So if I were you, i'd just stay away from the feet, but maybe just wrap them in hot or warm towels 'cause after all they do carry all that weight, and they also deserve a little break =)
hope that helps you in the future.
God bless and enjoy your little bundle!
