Not sure is this common or concerning so would be grateful for any advice:
Suddenly he has 2 days when he is kind of absent and ignorant toward us.
We are on milestones, except speech where we noticed some regression last few days:
-He imitates 7,8 animals
-He will say brm for car, baa for batery, bu for bug, ban for banana.
-However he regressed and stopped using mom/dad and njam for hungry, but he will still look at us when asked where is mom and dad.
Today he also did not wanted to wave at me and blow me a kiss, which he always does when leaving home.
This concerned me since I read all the bad things about regressions.
Are there the ones who are temporarily, common and normal, or should i pay serious attention to this?
