breast feeding bottles

So my son is 3 1/2 weeks old. We have tried soothie by Avent and first years he sucked but frowned. We tried latch and the flow was wayyyyy to fast even though it claimed slow drip and newborn 👎. We tried tommie tippee, he liked it but the flow was still kind of fast and he was getting upset. Off to Walmart we went to find something else. We bought the MAM because it resembles the nipple when in the mouth and flattened which mimics the breast when baby is sucking. He loved it! Drank non stop and never frowned up at it. Highly suggest the MAM bottles
