Girls, I don't even know what to think about anymore, we had runny nose about 4-5 days ago, it lasted for about two days and then disappeared, and today a tooth popped up on top of it, now again the runny nose and temperature is 37.5, I thought it was a cold last time but everything went away, now it's back on the teeth or is it really a cold, the little one is capricious, clingy, often attached to my breast, I spray in the nose... What else can you suggest? Tell me? I'm going crazy soon ???
