Gripe water and probiotics. Also a Gripe belt from amazon worked for us too! Lots of bicycle legs & circular tummy massages. Best of luck!
Are you breastfeeding or formula feeding? You can try changing your diet or their formula to help too
5 weeks old is hard :( poor baby. Gripe water, and as much movement in his tummy, kicking his legs for him, tummy rubs. You could also try feeding him less milk more frequently so he’s getting extra fluids :( best wishes!!!
