Ipad has been quarter half dunked into milk honey cereal

Read this support article for general guidance, particularly if you see an alert. --> If you see a liquid-detection alert on your iPhone - Apple Support (This is for the iPhone but I suspect it would be similar for an iPad.)

Even if the iPad is dry, milk can leave residue and it would be a good idea to have Apple take a look at it. Go to this page to find your nearest Apple Authorized Service Provider (AASP) or Apple Authorized Distributor (AAD) --> https://locate.apple.com/country

Water and electronics generally do not make happy bedfellows. Unlike an iPhone that has limited water resistance, an iPad is not designed to be resistant to water or other fluids. While an iPad may survive being splashed with water if immediately dried, it will almost certainly suffer irreparable damage if it is allowed to get wet, is exposed to prolonged moisture, or is submerged for any length of time. Other fluids that include sugars can encourage mould growth and/or cause physical buttons to stick or become completely jambed.

For reference, if the worst should happen and your iPad gets wet, speed is essential. It should be immediately dried with an absorbent towel - then set aside in a warm, dry location to thoroughly dry. The iPad should be turned-off - and no attempt made to turn-on, use, or charge the iPad until you are absolutely certain that the iPad has fully dried out. Pay particular attention to the charging port.

Never use rice as a desiccant to dry-out an iPad - as dust from the rice will cause more damage and promote mould growth. You can, however, safely use silica gel sachets as a drying agent.

You would be best advised to visit the Genius Bar at your local Apple Store or Apple Authorised Service Provider (AASP) - where the technicians will be able to test and assess your iPad - and if damaged, you can explore your available options:
