First Solid Gave her gas- advice?

Hi mommies- Our little one has been showing signs of wanting to start solids (she's almost 5 months). I have the baby bullet and used the first foods guide (4-6m) and whipped up some puréed peas.  the first feeding today was quick, she maybe had 2 or 3 bites and wasn't interested so we moved onto her bottle, the second feeding (maybe she was more hungry) she gobbled down the entire serving, smiling and laughing. Quickly after she had horrible gas pains. Crying...irritable...and lasted a few hours.
