Now, first off, we have to say - opinions on whether you should use a dummy at all are hugely divided.
There are pros and cons on both sides. Plus, some people who plan to use a dummy find their baby won't take one.
But if you are considering using a dummy, when is it safe to introduce one?
Dr Philippa Kaye told us: "If you are breastfeeding it is recommended to wait until breastfeeding is established approximately 6 weeks to avoid nipple confusion.
One of the mums on our forum, thirdtimemummy, told us: "My baby is breastfed and has a dummy to help her settle. It isn't a problem as long as breastfeeding is established."

If you're not breastfeeding you can introduce a soother from birth, Philippa says.
She adds that there is even evidence that using a dummy can decrease the risk of Sudden Infant Death Syndrome (SIDS, or cot death).
