I know you should not compare but my dd was talking very quickly and my ds who is 15 mth old is very quiet.
He says "dada" "mamma" "do-do"(dummy)"ta"
He also signs all gone and puts hand over mouth if he drops something.Also waves bye bye and kisses,hugs.
He understands everything I say to him but there is a lot of babble and despite saying all the usual "dog" "woof" when reading, hes not taking me up.He just seems to say doh to everything
Is it a boy thing (people keeping saying boys are slower)
He is a quiet little boy.My dd is very confident and he just follows her around...
