We tested the bottle with our grandson who is now weaned slowly. He has accepted the teat immediately and can hold the bottle well. When the bottle, the cap is tightly imprints on the go.
The next grandchild comes in two months, because we need again bottles when we treasure it, the Lansinoh Weithalsflasche with Natural Wave sucker in size M, we have already tested. For starters, we need the sucker-size S, this bottle we could also test yet. We know now many brands, because our daughters and daughters-have different bottles. A bottle of Lansinoh does not have any, we like it very well!
