Hey moms! I've posted yesterday in general health,posting it here as well hoping for more traffic. So,my boy is almost 4 years old( in november) he is very loving,smart,very social,sensitive and very cooperative child and i love him dearly! He sings a lot to himself sometimes to the point i get a headache and tell him to stop..then i feel bad..he tends to sing nursery rhymes but most of the time he is just singing it with no words ,just the sound,like douuu douuu dadaaaa if you know what i mean. Im just wondering if thats a "normal thing" children this age do!? Or should i get more into it? Im a worrier in general and i dont want to worry for no reason..any of you moms have children that do the same? But absolutely no underlying cause? I would greatly appreciate any experiences! TIA xx
