No don't you dare apologies ree!!
How dare they talk down to you...
Your concerns are valid they aren't nonsense and if they don't like being bothered with simple questions then maybe they shouldn't be in that line of work..
Make sure you discuss this with your mw k babe...
You are not nothing you are a mum!! And you are following your mummy instincts and that's far from nothing.
Huge hugs babe xox
