Muscle and toning.

So I've started my journey of getting this body back. I just had a baby almost 3 months ago and I don't really wanna loose weight. Just tone my body up. I do VERY light cardio at first and then go straight to weights. And follow up with proteins shakes. For food I usually just eat a bowl of cheerios for breakfast or eggs and then I eat chicken and corn or broccoli every damn day for lunch and dinner lmao. I'm not a good cook so I suck it up. It gets boring but whatever. Am I doing everything right so far? It's only been about two weeks so I'm not expecting results right away, but when should I start seeing noticeable results? And does my diet plan and work out routine seem good ? Any extra advice would be awesome. Thanks!
