Oh Katkins, cyber hugs to you. Losing weight sure isn't easy, and our lifestyle dictates how much time we get to do things about it, and you aren't the only one in your house to consider( ie DH is part of it too).

Don't feel too down, your bub is only 3 months and it is a slow road back to your body. Have you tried that stuff you can get from the chemist, it is a meal supplement and my mum is using it, my nana lost heaps of weight. The gist of it is you have it as 1 meal and there are some things you can't eat, and then just some walking whenever you can.

Hope you have some luck, and chin up!
Best wishes michelle
