I'm a single mum, my childs father very rarely contributes, some weeks I get somthing off him, but most weeks I don't
No I can't go threw child maintenence as he works cash in hand.
It's unacceptable for him not to pay regularly towards his child, clearly he thinks that it's your problem that the child needs supporting, so let it be his problem he works cash in hand and if he gets reported then it'll screw his little scheme up. Your child is entitled to support, they have 2 parents, one isn't pulling their weight and you and potentially the child are suffering for that. His work situation is not your problem, your problem is your shared child needs feeding and alone you are understandably struggling with that.
I obviously can't work as I have a small baby, and couldn't afford child care. Its hard
Are you getting everything you are entitled to? You may be entitled to free hours and childcare through UC if you do work, depending on how old the baby is?
And the thing is, I did have money for the milk, but I just thought that money could go on somthkng else like food and the milk I could steal
Are you regularly going without food or essentials yourself to afford the food and essentials for the baby? It's not uncommon unfortunately, I did it myself 20 years ago and times have got tougher since then. Again, food banks, health visitor, go, local charities etc can all help with that.
As for the moisturer, that was just greed I guess. Another thing I needed but didn't have the spare money for
Nicely, unless you have a skin complaint that's painful etc, you didn't need the moisturiser, I appreciate it was a moment of "Fuck it" because of the position you seem to be in, it's bloody miserable and something like a tube of moisturiser can make you feel a bit better, but you know it was wrong, you've been caught and hopefully that's the end of actions like that for you now.
Please do seek some help OP, you don't have to live this way.
