Congrats on motherhood! :)
regarding weight loss:
1. exercises: cardio workout & weight lifiting (you won't bulk!) and you must lift weights if you want to "tone" your muscles.
can't target just one muscle - for example lose fat on your abs - by working out you lose fat all over your body (although belly fat can be the most stuborn) - anyway always warm up (10 min), cardio workout (either long and slow, or fast and short aka HIIT - about 10-30 minutes), weights (work on all muscle groups: arms, legs, butt, chest, shoulders, back and abs) - and within a few months you will look like before pregnancy ;)
let me know if you have any questions.
