Look everyone, she knows it was the wrong thing to do, she has said so.
Many people make an error of judgement under pressure, and she is admitting to this here - she isn't the first stressed mom to misjudge a situation. I have made mistakes in my life too, I think most of us have. The important thing is that we acknowledge them and learn from them so we don't repeat them, not to hate ourselves forever......
OP, I am not sure whether anybody will contact you - it seems unlikely to me, but hopefully somebody from social services will post who has a better understanding of the likely response.
If SS does get in touch, it's vital you acknowledge responsibility and take on board any advice they give you.
I know you feel frightened now, but you aren't going to end up in prison or with your child removed from you or anything like that. You do need to engage with their advice however.
More importantly, can you identify what we're the pressures that led up to you making this decision. Are you finding it difficult to cope with your toddler at the moment - does taking her out in public stress you out? Or are you feeling exhausted for example and struggling to keep on top of things.
And if any of the above is true, is there anything you can change/anyone you can reach out to for help, to try and avoid an equivalent situation in the future?
Good luck.
