The past 24 hours my son has been straining sometimes when he's awake until he turns red/purple. I'm able to get him back to normal within seconds but it's still concerning. The strange thing is he doesn't cry about it or act very uncomfortable... He just gets focused. But he grunts in his sleep and when I see him strain I bicycle his legs and I can tell he feels much better when I do that. Just wondering if this is normal behavior? His stool is normal, going at least a couple times a day.
