1 month pp, need exercise advice

Pre-pregnancy: I am 5’2’’ btw

114 pounds

One month pp:

128 pounds

At 41 weeks, I was 150 so I am feeling good about where I am but I have hit a plateau with losing weight. I go to my 6 week appointment soon and will be able to work out. Tips on what helped you? What exercises and even nutrition worked? I am walking daily with my daughter!

I am breastfeeding and eat peanut butter,flax seed, chia seed oatmeal with strawberries and yogurt every morning. Is that too much food?

Any advice would be super helpful!

Right when we found out:

41 weeks
