Do you still remember that both nature and nurture affect a child’s development, which is a continuous process with a certain sequence that every child would go through? Children tend to exhibit certain characteristic behaviour at different stages, when you understand the characteristics and needs of your baby at this stage, you can set reasonable expectations and provide appropriate guidance to your baby. However, parents should remember that every child is unique. Children have their own pace in development and vary in their abilities. As long as your child’s development is generally in line with his age, you may not worry too much regarding the differences in performance between him and other children in individual areas. If you are unduly concerned, talk to your doctors or nurses.

Are the toys of your baby safe?

There are many different toys available in the market, what would you consider when choosing toys for your baby? The right toys should be safe and matches the level and needs of your baby’s development. Babies at this stage often like to explore with their hands and mouth, and they would continue to enjoy putting toys into their mouth before their first birthday. In order to ensure their safety, parents should take into consideration the design and materials of toys when shopping for babies. Let’s learn how to pick safe toys for our babies!

When choosing toys for your babies, you should bear in mind:

  • Rattles with small parts will be easily swallowed by babies and may lead to suffocation.
  • Pay attention to the safety labels on toys; make sure that the colours and paints used on the surface of toys comply with the safety standards. Paints that are not up to standard may contain heavy metal (e.g. lead). If children lick the paints constantly, they may suffer from chronic heavy metal poisoning.
  • Pick toys that are light in weight for babies. Do not pick those that are inflammable, fragile or rust easily.
  • Avoid stuffed toys. Stuffed toys are difficult to clean. Babies at this age do not know how to play with these toys. If stuffed toys are put on bed, they may cover baby’s face and lead to suffocation.
  • The edges of toys have to be smooth. Check the toys for any sharp edges or cracks often to avoid hurting your baby.
  • Clean the toys frequently, as babies like dropping them onto the floor and putting them into their mouth.
