Baby is gassy every evening

Darla

Does anyone one have any suggestions as to why my baby would be gassy only every evening. He bottle fed with formula and breast milk. I've very diligent on burping. But he does have a paci I'm wondering if that's part of the cause. I know it's gas because as soon as he flat he fusses. So try putting a baby to bed like that lol. He's three weeks old. Thanks.
