Hi,
I am planning not to bring a dummy to the hospital at least, but probably will use one when the baby is a bit older. My parents never did manage to wean me off my thumb
The advice from UNICEF and the Baby Friendly Guidelines are that if you want to breastfeed the baby shouldn't be offered a dummy or teat until breastfeeding is well established (about 6 weeks of age). The idea behind that reccomendation is possible 'nipple confusion' - that the baby will get used to the plastic teat and not attach to the breast so well. Some baby's seem to experience this and others can manage both techniques from day 1 no problems. Unfortunately you can't see beforehand which type of baby you've got
For those planning to bottle feed a dummy is certainly a possibility because most babies get all their milk fast from the bottle, then still want to suck longer even though they're no longer hungry.
Of course, in the end this is entirely your decision
All the best,
Goosie
