13 month old doesn’t care to walk...

My 13 month old still hasn’t walked. He can pull himself up while holding onto furniture. He can get around walking but only when holding onto the couch or table. He doesn’t want to use his walker (not the one you sit in). He doesn’t want to try to stand on his own. Whenever I try he just ends up sitting down. Sometimes we will walk around the house by me holding his hands, occasionally I will let go of one hand. But he usually will start looking for it 😂 but lately I’ve noticed he does even really want to do that much anymore. He will just bend his knees and pull himself down to crawl if I hold him up.

It’s a little frustrating 😢 anything I can do?
