My baby is behind…

I feel awful but I just realized my baby is a tad more behind than I originally thought.

They are 14 months old and they don’t really understand words, doesn’t say words directed towards anything, doesn’t really show affection, doesn’t wave, clap well, play peek a boo, struggles with solids, and doesn’t respond to their name. I never realized their milestones were behind until a random search thinking about how excited I am for them to talk.

They are walking, climbing, and babbling.

I’m posting if anyone has experienced a toddler who is behind? What all did you do to help them?
