Mine was 10 months however I’ve heard that it’s not something to be super concerned about until 18 months. If he is pulling himself up and walking while holding on to things then I would just give him time, he’s headed towards it. You could try finding more mobile toys or things that he could stand and walk with support. If he is a quicker crawler he could be impatient and want to get somewhere faster
13 months. My son’s pediatrician said that as long as they are showing signs of progression and trying then it’s not a worry until 18 months
Just wait till he’s ready to fully walk himself, you won’t need to do anything to encourage that. My son started walking at 18 months even though he took a few steps at 14 months
