My ipad isn’t charging no matter what i do and ive tried everything this has said and we only got it around 4 months ago

Did you try a hard reset?

1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Then press and hold the Power button until the device restarts.

if nothing works and its under warranty, contact apple support:

If you are having difficulties with charging your iPad, consider that the problem may be with the Power Adapter, cable, or iPad. These support pages should help with troubleshooting:

Charge and monitor the iPad battery - Apple Support

If your iPad won't charge – Apple Support

Troubleshooting generally requires substitution of the Power Adapter and cable for another known-good item.

Try a different brick, try a different cable.

you might try restarting or resetting
