Baby babble

Good morning! So I am extremely concerned about my child’s lack of “talking”. He used to coo constantly, and carry on full conversations with me. 14 weeks now, and probably for the last two weeks he doesn’t really make any noises. He will let out soft gurgles every now and then. I’m just nervous about this regression, and don’t know if it’s normal or not. I know they’re supposed to start babbling at 4 months, but I don’t think we are going to be anywhere close to that. Help ease my anxious heart.
