For many babies, this is all they have.
The formula milk that's their daily essential.
The boy in this buggy needs it, but his parents can't afford it.
We manage our money normally.
It's just when we're really desperate.
She wanted to breastfeed, but her son wouldn't latch on, so he's entirely reliant on formula.
The high prices are driving his parents to do whatever they can to keep him fed.
It's wrong.
And it makes me feel horrible, stealing.
But you've got to do what's right for him, because he needs it.
You can't give him anything else.
It's the baby's father who goes out to get it.
If it was a case of stealing or having your baby go about, you would steal.
I know you would.
You might hate it.
There's no way you'd let him starve.
It's theft, but I think it's criminal how much they charge for this stuff.
You can see on the supermarket shelves just how much security is now in place to deter shoplifters.
But at the Hartlepool Baby Bank, they are in no doubt.
The high prices are putting babies at risk.
People are doing a lot of unsafe practices to get hold of formula.
They are swapping and chopping and changing, and we do not recommend that.
We've even heard families using tubs of condensed milk.
That is not suitable for an under one.
You're in no doubt that there are families who just aren't able to put their hand up and ask for help.
No, because of the shame, the stigma, the fear of trolling, the fear that social services may get involved, the fear they may lose their child.
Families are also searching online for cheaper options.
It could have been mixed with anything.
It could be half a tub, it could be out of date, it could be lidded with bacteria.
So that packet is actually open?
It shouldn't be allowed that we're selling open formula because the health risks for that child can be quite severe.
This could be a baby who ends up in A&E needing a drip because they could get such a bad stomach bug, they could get too dehydrated.
It's horrendous, and there's a lot of it.
Baby banks and charities across the UK have described this to us as a hidden crisis.
We put a lot of focus on the need for breastfeeding support, quite rightly, but that now needs to be seen as a completely separate issue to this.
All these things that are happening are putting us on the brink of a public health crisis.
If we are seeing families watering down milk, using condensed milk, buying potentially opened tubs of formula milk online, the genesis and safety of which cannot be guaranteed, then that is a very, very serious problem which puts baby's health at risk.
The formula milk manufacturers say they realise how stretched family budgets are, but say their production costs have significantly increased.
The Westminster government also says it recognises this struggle and it is helping with the cost of living.
There is, though, no plan to increase the value of healthy start vouchers.
But when the health of British babies is under threat like this, it can't lurk in the shadows any longer.
