Just been to the doctor and she said that it isn't a urine infection as she didn't have a renal problem at birth which would cause infections in babies. She also checked her ears, eyes and throat to see whether she had a cold but they were all ok. She also checked her temperature which was fine. She thinks it could be something I'm eating which is affecting my breastmilk which is making her wee smell. I do also give Poppy formula about twice a day and have recently changed to Aptamil for hungier babies, so I think it may be that. So I'm not going to worry now especially as it appears quite common (thanks girlies for easing my worry!!). The doctor has now given me the ok to have her immunisations at 12 today and I'm not looking forward to it!
