1. Keep your food sources in metal or glass containers with secure lids. Mice can eat through cardboard, certain plastics, and other forms of containers to get at food. In order to cut down the mice's food supply, make sure that you don't leave any food out, or if you do, to put it in something that mice cannot get at.
At 18 months, children typically use around 50 (but we don't worry too much unless they have fewer than 10-20). At 24 months, children usually have an expressive vocabulary of 200-300 words (but we don't worry too much unless they have fewer than 50). At 3 years, children can have anywhere from 500-1,100 words in their vocabulary. By 5-7 years, children have an expressive vocabulary of 3000-5000 words.
When your little one does start talking, you can expect words to come slowly at first. Typically, children have around 4-6 words at 15 months and then between 20 and 50 words at 18 months. When your child hits the magic 50 word mark, he will enter a language explosion during which he will astound you with his ability to quickly learn words that you didn't even know he'd heard!
