Is this symmastia or the beginning of it? It seems like I am getting uniboob. (Photo)

I agree with the answers given that this is not symmastia but rather skin stretching and thinning.  After you are done having children and breastfeeding, you can have revisional surgery with textured implants placed further apart to give you some space between your cleavage.  The textured implants stay where your surgeon puts them.

I believe your photos show some pocket stretching (and thinning of the overlying tissues) on at least one side, and possibly both. Removing your implants may solve the symmastia issue, but will create a new and even worse deformity with deflated, skin-stretched breasts.Why not wait until your are done breast feeding, see how your breasts look 3-6 months later, and then consider whatever you and your plastic surgeon decide is best to deal with any issues you have?In the meantime I would recommend avoiding tight, push-up, or stretch (jog) bras that push your implants towards the middle. Supportive brassieres would be better than compressive ones, the latter only worsening the problem."Uni-boob" is only a relative term, and actual conjoining (two implants in one pocket) is extremely unlikely.Please be patient. I feel that additional surgery is recommended, but not until your breast feeding is complete, your breasts have returned to their new "normal," and an appropriate surgical plan created to deal with any and all concerns with (hopefully) a single operation.

Your breasts can change a lot during pregnancy and after breast feeding. The skin can certainly get stretched quite a bit and it can cause rippling. I think it is too early to plan on any revision. Enjoy your time with your child.
