My son is 12 months old and seems to have zero interest in standing without holding onto anything. We try and practice standing solo and he will legit pick his feet up (almost like he’s sitting in the air lol) so we can’t stand him up or immediately plops onto the ground. He pulls himself up and walks along furniture all day long, but refuses to try and stand by himself. He has no interest in pushing walkers or walking with assistance from my husband or I. Should we just let him be for the time being?
