Trying to lose baby weight, kick pnd in the butt, and get my life back

I'm a 31 year old mum of 2 (baby and young toddler). Having 2 kids in 17 months has changed my body in so many ways and I'm just now feeling I'm in a position to get myself back. Sleep deprivation and having NO TIME notwithstanding.
Trying to do this within my limits, so no gym or dedicated exercise time (see previous reference to NO TIME), but lots of walking while pushing 22 kg of children, and keeping track of food.
I need help though. Hoping to get some motivation and advice here!
