18 months talking state

M

My LO says only da and mum but he understands each and every complex 2-3 sentences long instructions of mine and follows them to the T.

Gets all his work communicated and done by pointing, signing etc. No hindrances

Every other milestone on track.

When I ask him say book/color etc whatever he makes ha /ae sounds but no words. Gets all his work done with actions

Anyone in similar boat ? Any late talkers ?
