V.B.
No, I can't say I have ever heard of it. However, I used the kegels and they worked fine.
I know some women use some sort of Vitamin E oil prior to delivery to help with the stretching to try an avoid tears, but that doesn't sound like what you are talking about. One interesting thing, you might keep in mind though, if it is worrying you... it was easier the second time. My 2nd delivery went faster (admission to the hospital thru birth in less than 4 hours, while my first at the same stage at admission it took more like 6 hours). Our 2nd baby was a little smaller (7 lb 6oz instead of 8 lb 12 oz) also. With the first child, it seemed like (I hate to be gross or to much info) my insides were "saggy" for at least a week after delivery.. walking around the block was uncomfortable even. With our 2nd, I felt like I could have run a marathon before even leaving the hospital. The kegels seemed almost unnecessary!
Now, my babies were a little farther apart than yours (just 3 weeks shy of 3 years, delivery to delivery).. so I don't know if that played any part. But, if you are expecting things to be worse than the first go round, that isn't necessarily the way it will go. You just never know. Labor was completely different sensations (all natural both times, but the first I felt like menstrual cramps and back pain, the 2nd time it felt more cervical bone pain - completely different). But labor was easier and faster, and so was the recovery...
So even though everything could go just like the first and you might expect a longer recovery b/c you are 2 yrs older now, that isn't necessarily what will happen. So don't stress out if you can't locate this manjakani (ointment I'm guessing?). (of course if you can and it works that's great!) But, you may not even feel the need to bother with it when it comes time...
Congrats on number two...
God bless you!
