Monster Jam Toys are for people of all age groups. The cars and trucks under the brand "Hot Wheels" are generally for younger children, ages 3-5. Other Monster Jam Toys are for children ages 5-13.
Children from the age of 0-2 get in for free as long as they are with an Adult
Leapfrog Toys are only for young children. The youngest age groups is for children 0-3, the middle 3-6, and the oldest 6-7. All toys are very educational and helpful for young and growing children.
Riding toys are usually targeted towards younger children in the age groups under 8. Some ride-on toys are mechanical and require hand-eye coordination and are geared towards the older children.
These toys are marketed for the age group of three to sixteen. Children younger than this age group should not play with these toys as they can pose as a choking hazard.
It does not seem that there is a specific set age group for hovercraft toys, but I would highly suggest an older, 5-10 type of age group. Get an idea of them here. http://www.nextag.com/Toys--zzwholesale+radio+control+hovercraftz2700600zB6z5---html
The Leap Frog website have different groups of toys for children from birth thru 8+ years of age. Having had a child growing up using this brand of your, I would suggest that 8 is the upper limit.
The packaging will tell you the age groups, and if they are safe for your child's age. Always read the packaging.
LeapFrog electronic toys are especially designed to withstand much wear-and-tear from toddlers and preschoolers while maintaining their quality. Since they are specifically geared for these age groups, the design and material that go into making them will withstand the abuse from younger age groups.
These toys are made for different age groups. Normally 12 months is the average age children start with blocks although at that young of an age you cannot expect to much from them, at age 3 they should more than likely be building with the blocks.
I think the best Monster High for 8 and 10 year olds probably would be the Monster High 13 Wishes Gigi Doll. It looks appropriate for little kids of that age.
Toys and of course party supplies. Toys R US is a known toy store which offers toys for all age groups and accommodates every need of any child. Including celebration supplies.
Which type of toys? Ones with small parts you want to wait until they are about 4-5 years but companies make toys for certain age groups and i think you should follow those guidelines.
