oooooh I know. Trying to see a hv can be really difficult especially if you work. Also getting them to answer a phone is even harder . I do not mean to upset any hv's out there. I would definately take her to your gp rather than hv. Gp can refer her on.
Not sure how old your DD is but turning the foot inwards is very common when children first walk and is usually nothing to worry about. It is usuually a maturity thing which corrects itself as they get older and more experienced and confident with walking. If it continues to be marked then a physio will be able to assess whether or not it needs treatment.
I cannot for the life of me understand why a HV sitting idly could not have dealt with your query on the spot. + (irritated emoticon)
