All is welcome Janie... it is great to get all extremes (hmm not quite the word but you know what I mean).

babies put all their effort into making sure the most important thing is well developed, the head, which is why babies heads are generally normal size even if early

DD1 was 11 days early 7lb 5oz head 35cm 50cm long
DD2 was 3 days late 8lb 1oz head 33.5cm and 49.5cm long
This is great info Jols, exactly what I wanted to hear, makes sense .
