Midwives have seen it all and won't judge you either way. Waxing does increase the risk of infection as each hair is torn out of it's follicle small capillaries are broken allowing germs to enter and grow forming pustules. Ingrown hairs are also more likely and these too often are a site of infection. Make sure that your undies are not too tight because this can lead to an increased risk of ingrown hairs.

Personally I opted for a trim rather than a wax and I think that is the most common scenario. It can be hurtful to read that your choice to allow hair to grow in that area is "yukky" and it might be more tactful to refrain from posting those types of comments. Lots of women give birth with the natural amount of hair and that's fine... I can understand how it is probably a more "modest" aesthetic to keep some hair... some women feel more "naked" with every fold of their most private parts on display... a bit of hair serves to cover that up.
