Hi, Paediatricians encourage to introduce babies to stuffed dolls and toys, which also become their favourite toys most of the times. They say that they help in forming a connection and familiar objects also ease transition later on. Push toys, fur toys, balls (big enough to avoid choking hazard), kitchen utensils. Here's a link that has number of brain developmental toys that you can get for your baby. http://www.amazon.in/s/?ie=UTF8&keywords=baby+brain+development+toys&tag=googinhydr1-21&index=aps&hvadid=147994744764&hvpos=1t1&hvnetw=g&hvrand=16728559000318092420&hvpone=&hvptwo=&hvqmt=b&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1007801&hvtargid=kwd-11911924621&ref=pd_sl_73oy0drrnj_b

there are lots of toys that you can let your baby play with between the ages of 7 months and 1 year. there are lots of sensory balls that your baby can play with. push and pull toys are also great. other than that, you can get stacking toys, grouping toys, dolls, simple toys with music and light and so on.
