Gas from solids?

[JessesGirl29]

I don't know where I'm going wrong or if anyone else had this problem. My night time routine is so solid and has been working out great. I wait until he starts to get a little growly at night, and offer him a variety of foods and I give him as much time as he likes and usually end off helping him with yougurt or giving him fruit.
Then he gets grumbly and I ask him if he's ready for 'splash splash' and he smiles and we transition right to bath until he's unhappy and then in to his room, wind up a musical toy, breastfeed until asleep then I transfer him in or I his crib and he wakes a little but settles.

My problem??? Gas!!! Gas has never been an issue since newborn days and when breastfeeding at the end of the night I can hear it and feel it moving all around. I feel like it definitely disturbs his sleep as he's up a lot and I hear it but can't get it out! No amount of burping or bouncing or anything helps.

Is it that I'm making two 'meals' so close together? Just his stomach adjusting to food? Could it be one thing? I noticed when he did baby cereal if I gave that at night same issue. He has to have it in the morning.

Any idea?
