Q. I have a 6 month old daughter and I am getting concerned with all the recalls in infant/toddler/children's toys. If you also have any great ideas about bottles and so forth. Much would be greatly appreciated.
A. Melissa and Doug . . . . AWESOME toys that are made in America and can be found at Toys R Us. Their products are also high quality and usually wooden (as opposed to plastic). They also focus on educational value as opposed to TV character association.
Quote from their site:
"Additionally, we specifically test our paints and coatings very frequently, to be sure our toys meet or exceed government recommendations limiting heavy metals and lead in children’s items. We have cabinets full of thousands of passing test reports, and these passing results have been verified by 3rd party independently accredited testing laboratories, considered by many to be the best scientific laboratories in the world."

What are some activities I can do with my 14 month old?
Q. I am a SAHM with my 14 month old daughter. She is a very busy girl and I am finding that she is getting really bored with our usual activities. She likes to play outside, but it is really rainy for most of the year where we live so going outside is difficult. She also puts absolutely everything in her mouth so crayons, paper, etc, won't work. We read books a lot and stack blocks and stuff, but she really doesn't really play with many other toys. Any real suggestions would be great! Thanks!
A. Keep offering the crayons and coloring books, just discourage her from putting them in her mouth. That is how she learns!
Puzzles (the wooden ones with pegs are great for that age).
Blow bubbles.
Google the recipe for edible playdough.
Look for Story Stretchers on Amazon. There is a version for infants/toddlers. It gives ideas to turn favorite children's story books into math, science, games, music, arts and crafts and even snacks!
If you can, look for an activity such as Mommy & Me gymnastics or Gymboree that you both can participate in.
Look for a local playgroup at http://groups.yahoo.com
If you can, visit the local petting zoo, children's museum, etc. Most book stores and/or libraries have story times for little ones.
Sing, dance, let her help you clean (my little one would help 'fold' the wash cloths, likes to take a baby wipe and 'dust' the fireplace insert, etc).
Purchase some musical instruments, puppets, etc.
One of my last few answers might have some other ideas you want to incorporate, so check that out-it is for an older toddler, but a lot you could probably use as well.
I hope this helps, and wish you the best!

How far above its equilibrium position will it go?
Q. An infant's toy has a 120g wooden animal hanging from a spring. If pulled down gently, the animal oscillates up and down with a period of 0.50s . His older sister pulls the spring a bit more than intended. She pulls the animal 30cm below its equilibrium position, then lets go. The animal flies upward and detaches from the spring right at the animal's equilibrium position.
If the animal does not hit anything on the way up, how far above its equilibrium position will it go?
h=_____cm

h=_____cm
A. By ω = √k/m
=>(0.50)^2 = k/0.12
=>k = 0.03 N/m
By the law of energy conservation:-
=>KE(max) = PE(spring)max
=>1/2mv^2 = 1/2kx^2
=>1/2 x 0.12 x v^2 = 1/2 x 0.03 x (0.3)^2
=>v = √0.0225
=>v = 0.15 m/s
=>By v^2 = u^2 -2gh
=>0 = (0.15) - 2 x 9.8 x h
=>h = 0.001148m
=>h ≈ 0.12 cm
=>(0.50)^2 = k/0.12
=>k = 0.03 N/m
