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.
At the start of this period, most kids can follow directions and say 50 or more words. Many combine words in short phrases and sentences. By age 3, a toddler's vocabulary usually is 200 or more words, and many kids can string together three- or four-word sentences. Kids at this stage of language development can understand more and speak more clearly. By now, you should be able to understand about 75% of what your toddler says.
