Tips to encourage more water consumption in toddler ?

My LO is about a year & 1/2. We only offer water & occasionally milk at meal times. I always make sure he has a cup of water available & in sight to try to keep it top of mind. I ask through out the day ( he usually tells me no)& even try to lead by example (“let’s both take a drink now”). But we’ve been potty training so I see his pee & it’s soo yellow! He needs to be drinking more but he just doesn’t want to & it’s not something I can really force. Anyone have a trick that works for them?
