My little lad is 3 weeks and fully breastfed. He poos frequently throughout the day sometimes in every nappy with runny mustardy yellow poo which I understand is usual for B fed babes. However he seems to struggle to pass his poo with very load grunting and straining that can disrupt his feeding, sleep and alert periods... i.e. he will be sleeping soundly but will be disturbed by strng straining and pushing sometimes for long periods of time. I have tried him on Infacol which has helped with wind but not the straining... the HV does not seem concerned but has anyone got any experience of this or tips of how I can ease things for him? Thanks
