My twins are 11 weeks old, and the night feeds can get a little crazy when both boys are screaming at the same time, so i just bought a tommee tippee perfect prep machine. But since using this, one of my twins have become very agitated during feeds, won't settled after, sounds like lots of air in his tummy and I struggle to get him to take his whole bottle now. Is this a coincidence? We have only used the machine for 4 feeds so my partner said I'm over thinking it.
Any advice would be greatly appreciated.
