Reduced vocalization now in 6 month

[vgahdmi123]

He was very loud baby, making noises and cooing all the time and on everything literally, on walls, ceiling, people, bulbs since the 2nd month.
However, in past 3 days vocalization is lower, we can still hear him cooing but here and there, not always like usually.
Is this common behavior that happens or should I be concerned?

I don’t think there’s any reason to be concerned. They go through phases of practicing one skill for a while and then focusing on another. My little one used to scream and shriek and then suddenly stopped and now every couple of weeks he’ll do it again for a day or two. Just keep chatting to baby and they’ll be learning how to talk and will be chatty again soon.

Have he ramped up his attempts to get moving recently? Rolling more? Trying to crawl? Both my children done this when they were trying tO move, I think they can only really focus on one thing at a time. In fact I noticed with my son (he’s 9MO now) that he would only really babble and “talk” in his high chair, car seat, baby walker etc when he physically couldn’t move! He’s mastered crawling now and back to being a very chatty boy.
