Hello,
If she is truly crying when she passes urine, she should see her
pediatrician because that's pretty unusual in babies. And take there temperature. But if she is already crying, getting upset and then peeing, that is normal.
All the muscles in her little baby body tighten when she's upset and then release (including those of the bladder).
On the second matter, often babies are congested in their noses for awhile because they are still learning how to feed and their muscles are immature.
So instead of swallowing everything down cleaning, their muscles aren't so coordinated so when the tummy muscle squeeze - some liquid goes back up into their noses and far back nasal passages.
Then this makes congestions and
sneezing so it will eventually come out. If she is growing well and doesn't have
fever, that's probably all there is too it.
You can use the drops/vaporub if you think it helps, but usually it just goes away with time. Sometimes until after solids start between 4-6 months. I hope that helps.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr. Lisa Baker
