I don't want my baby to start using a pacifier because it's hard to stop once babies get used to having one.
I've heard people say it's hard to get a baby to stop using a soother once they get started, so I don't want him to have one.

「一度おしゃぶりになれるとやめるのが大変だから、使わせないようにしたい」
pacifier で「おしゃぶり」
to get used to ~ing で「〜するのになれる」

「おしゃぶりは使い始めるとやめさせるのが大変と聞くので、息子には使ってほしくない」
soother で「おしゃぶり」とも言えます。
