Any ideas for a gutz at 17 days old?

[puppies]

I have a 17 day old boy who loves his milk so much that he gutzes it down. I have since been pumping into a bottle so I can at least regulate how much he is getting as my boobs seem to fire like water pistols down his throat and he sometimes gages on it. I both BF and FF. Usually a the formula feed in the afternoon and evenings. Its about 50 50 actually.

Anyway, I get worried that he gets wind pain because he gets his milk too quickly. We use the nuk teats 1-3 months and he seems to like those better than then Avent ones but has anyone else got any other suggestions on how to slow him down or have they experienced the same thing and found a possible solution?

When Bf lean back till let down has finished and he is drinking more slowly..

for botle feeding sit him upright a little bit more and make sure the teat is full of milk ..

Thats the only 2 suggestions I can offer for the wind issues
