“mommy brain” – it’s a justification for why I forget things. I haven’t used it myself but our secretary uses it often to justify why I forget things. I think there is some truth to the “mommy brain”. My body is too busy making a little person to remember why I walked into my boss’ office.
“but I’m pregnant” – it’s a good thing to say when the husband is giving me a hard time for not riding my bike to work (6+ miles each way, uphill both ways) or when I want to watch something on tv while he wants to channel surf. It doesn’t work 100% of the time but it’s pretty effective.
“it’s what the baby wants” – one of my favorites. This is usually 100% effective but I try not to overuse it. Unfortunately the husband now claims to also know what the baby wants and it’s often in contradiction to what I understood the baby to want (Indian food for dinner, going for a walk).
