I had my dummy til a late age, hence why i didnt want Emmy to have one, but my mum told me i only ever had it for sleep and after i got to 7 or 8 months i didnt take it out of the house. She NEVER let me speak with it in, or smile lol, in fact there is not one picture of me with a dummy even though i was *whispers* 6, before i gave it up!
I also think dummies played a huge part in me still breastfeeding, my little one is a 'sucky' baby and was constantly feeding, with an older child this wasnt practical at all, and i was so tired i came very close to giving up feeding, in the end my mum bought me round a pack of dummies, steralised it and gave it to me, i gave it to emmy in the end and cried my eyes out (baby blues didnt help!) but Emmy is 14 weeks and still fully breastfed - i too would pay lots for a dummy!
