We hand reared a piglet 2 years ago, kept it in the kitchen infront of the aga, I think the number 1 tip that we werent told is to wean it onto a bowl or plate as soon as you can.
Our piglet got addicted to the bottle and we couldnt get it to drink out of bowls till it was maybe 8 weeks old!!!
Also I wouldnt have one in the house again, I would put it in a stable with a lamp
Ours got very pushy and slightly aggressive, also when it was coming up to bottle time would start screaming its head off at the loudest pitch I have ever ever heard in my life!!! This would just get louder and louder until the bottle was given to it, between the ages of 5-8 weeks it was a nightmare but my mum was attached to it, when it started biting feet to get food I chucked it out in the stable to spend the night with its litter mates and it never came indoors again!! it also was a bit large to be indoors at 8 weeks old!!!!!
You can get piglet replacement milk, and after a week turn it into a very runny porridge and put it on a plate for the piglet to suck off, he will learn quickly to eat from a plate, and the porridge can be thickened until its quite thick then weaner pellets can be added (in porrdige form)
We fed piggie from the bottle every 3 hours for the first week and then 4 and the 6 etc, however I realllllyyy wouldnt use a bottle for that long again!!!!
Good luck with your piggie
