My DS is 7mths and we have tired a number of vegs & yoghurt & farex without issue. But on Wed I gave hime home prepared buttenut pumpkin and a couple of hours later it was pooed out in pretty much the same form that it went in. That night he slept poorly & was up every three hours. I didnt make any connection. Yesterday he only ate a 1/2 serve and outright refused to eat the rest. So I gave hime mash potato which he scoffed. Well last night he was up every 30min crying with severe gas. Have I missed something, are you only supposed to give the blue pumpkin, is there something wrong with the butternut or just my DS having a bad reaction? Has anyone else had a prob with butternut?
