Really struggling with my weight..

I was always never anything more than a size 6/8 my baby was born at 38 weeks and 2 days. She was a teeny 5lbs 11oz. Although my bump did get larger towards the end I’m now probably between size 10/12. I feel so uncomfortable in my weight and appearance! Feeling so insecure and just feel silly for Moaning but its not shifting.. nearly 7weeks pp.

Anyone got any advice? What did you do? Things I can try. Getting out takes the life out of me with this little one :(
