1. Ensure that all bottle parts are completely dry before filling with milk or warming up the bottle. This will help prevent leakages from the bottle base.
2. When warming up the bottle, please unscrew the bottle top (but leave it on the bottle to avoid contaminants from falling into the bottle) to release pressure buildup. This will help to avoid leakages from the bottle base.
3. If switching between bottle and breast, we recommend to use either Size 1 or 2 Teat, as teat flow for these sizes are more similar to mother?s nipple compared to our faster teat flows. This makes it easy for baby to switch between mom and MAM. There is no need to upgrade teat size as baby grows as mother's nipple flow stays the same through the entire time she is breastfeeding. Just remember to replace the teats regularly for hygiene purposes.
