I would be inclined to go with this. They've not addressed the practicalities of the baby you raised in the circumstances of parked cars at the time.
You can also say you paid to park.
There are also the odd markings but not sure about this unless you can go back and take pics with no cars there - maybe old markings are showing.
If this were to go the tribunal they would also have to produce a correct traffic order, which often trips them up.
See what others say.
