Been feeling a bit down...

after having my second baby. My body’s not bounced back like it did after my first I suppose I just expected it to and now I have some excess skin above my belly button. I formula fed my first and I’m breastfeeding my second and can already see some stretch marks on my boobs so expecting them to be horrible saggy deflated things after. Just not feeling confident about myself anymore I am 27 and I’m feeling like iv aged. Have a 7 year old and 15 week old. My baby won’t take a bottle so I don’t get a break, find myself hiding in the shower sometimes to get a minute to myself. I just miss being me feel a bit lost. Just needed to vent sure it will get better soon.
