Baby K (3m) has had one teeny BM in 9 days. I've given probiotics, gripe water, even prune juice. His farts are horrendous! We've dove bicycles, tummy massage. Idk what else to do. With each day going by, I feel like his gas gets worse and worse smelling and he's increasingly fussy. I hate our new ped office, so I'm hesitant to take him in. Any tips?
