My MIL passed down to me baby milk bottle that she kept for 4 years (I supposed it's 4 years as my husband's nephew is presently 4yo). She said can just replace the teats.
1. Isit advisable that I buy brand new bottle and not just replace teats?
2. FTM here. Is the attached picture - a milk bottle steriliser or steamer?
3. Which one is better - milk bottle steriliser or steamer. Why?
TIA.
