Now, what we're really saying is that 50% of all babies have fully mastered all the skills needed to crawl by about 7 months. What this also means is that any baby taking longer than 7 months to crawl, is still learning other basic skills or becoming physically stronger.bviously there are 2 answers to this question. Firstly, about 50% of all infants can crawl at 7 months; 75% can do so at 10 months and 90% of all infants have mastered it at 11 months.
A rotten taste could be related to halitosis, also known as bad breath. Bad breath is an unpleasant condition that can be cause for embarrassment. If you don't brush and floss daily, particles of food remain in the mouth, collecting bacteria, which can cause bad breath. Food that collects between the teeth, on the tongue and around the gums can rot, leaving an unpleasant odor.
With the information in your last post this begins to make sense. Rotten egg smell is usually indicative of hydrogen sulfide (H2S) not hydrogen. There can be things in the water that react with the anode rod to create that gas. Sometimes changing to a different composition anode rod solves the problem and sometimes not.
