Welcome Kirsty.
Wish you lots of luck. You can do it. I hope to hear about a baby underway soon. Aidan must be a very nice one. I have a teen ager and thinking that is really all I can handle
Eating and watching TV.... I know what you mean it is cozy but it is not always what is right to do. Try drinking water instead or doing some exercises while watching TV or turn the TV off.
