Toys can be a tripping hazard if you have too many of them, and a chore to keep organized. To contain the chaos, buy fewer toys and set aside some of the bounty from holidays and birthdays to be taken out later. After the first group has lost it luster and you sense that your baby has gotten bored with that batch, bring out the sequestered toys, and so on. Toy cycling helps constantly refresh your baby’s interest so that what’s old seems like new again and can make less seem like more. But remember to play with your baby with the toy. You’re your baby’s favorite toy and the social interaction your baby gets from playing with you bolsters brain development.
