my baby is 6 months old. offlate he has been straining while passing urine. he is urinating a lot as well. I see his wet nappy every 5 mins. when he puts pressure many times drop come out. I also noticed a white glue like sticky white thing outside his genital area. did his urine test as well as ultrasound which came normal but am unable to get it why is he putting pressure while urinating. can you please guide what to.
