I get what you mean about worrying about being able to actually say it to people but I reckon the strong mumma bear you are will come out and you will get the assertiveness you need!!!
I totally agree! dh and I have one priority and that is our family. ANYTHING that we may not have said to people in that past now gets said because you know what? Our DS is too important NOT to say it!!! (yes that is worth 3 x !!!) lol Speak up hon, your words are your power. Not sure if you missed it in my last post but I'm gonna say it again anyway. Stand up and speak now or you'll forever be worring about the behaviours of those family and friends around your baby
