To ask how you would respond to this

[MmmMmmMmmmmmmmmm]

Text sent by your adult daughter (who has a one year old child)?

"I'm feeling very upset today. Overrun with guilt for leaving child everyday to go to work, I wish I were able to spend each day at home"

Please tell me "hahaha" isn't norm. Feeling like I've got nobody to turn to for emotional support.

Why do you only get some support from your husband.Have you talked to him first ?
My daughter is only young but if it were her I'd probably reply that I remember,it is tough but gets easier.
If you want a chat then call,pop over for a cuppa if you can.Or are you really asking for child care?

Was your mum a working mum and could she by any chance see your message as a criticism of her choosing to or having to work when you were young? Or were you raised in a 'skint' home with a SAHM and your mum thinks you could afford to stay at home but choose to work for 'the lifestyle'?

I was a working mum who would have liked to have been able to stay home, but it wasn't feasible. My response to you would have been something along the lines of "I know how you feel, but sometimes life just doesn't work the way we want it to".

This is a sad one.
Does your mum work as well? The pressures of modern life really do mean most of us have to work to provide for our kids. Every out-at-work mum feels like this from time to time. I hated it when I was at home. I longed to get back to work where I could talk about normal things with people whose second word wasn't always baby..
If it's really ruining your life, look for another job or see if you can work from home or yes, condense the hours. All you can really do is try not to make the same mistakes your mum did - and be there emotionally for your child when she grows.
