[ozmidwifery] thumb or dummy!?

[J Stewart]

Dear List(s)!   Just looking for a little bit of general advice on an old debate! I have a six month old baby cousin [very cute!] she has taken to sucking her thumb as she is starting to get some toothy pegs! and her mum is not in favour of giving her a dummy. I was wondering what opinions are on this? I would think that sucking thumbs could effect tooth development and the direction/position in which they grow, as well as forming a hard to kick habbit in todlers, but have also heard interesting points against dummies.   Any thoughts!?   Thanks in advance! Jessica.
