We did use the Mam pacifier, pigeon brand, nuk and simba too - we started around week 4 and after 6 months we decided to stop all pacifiers and we did that by snipping the tips off. I would suggest try to avoid pacifiers where possible. All of them have the propensity to misalign teeth, although the Mam’s one has least likelihood to do it since it was developed by dentists. Whatever pacifier you choose make sure it is bpa, phthalates, PVC and latex free.
