Role Of Parents In Handling Baby Development Red Flags

Here are a few tips and activities for encouraging and supporting the little one:

  • Show positivity towards your baby. In addition to this, be excited, talk to them, and smile when they make sounds.
  • Read and sing to your baby as it will help them understand and develop language.
  • Spend some time holding and cuddling your little one. Show a sense of care and security. Moreover, responding to your baby or picking them up doesn’t mean you are spoiling them.
  • As they turn 4months old, you can allow them to take safe things in their mouth. That’s how they learn and explore!
  • Give them a safe area in the house to play with toys – reach out for them or kick them.
  • Copy your child’s actions. If they coo, you coo. When they smile at you, smile back. Because these things help them build their first social skills.
  • Point out new things around your baby. Show them a plant on your balcony or the sky, cars, and animals.

In A Nutshell

Remember, there isn’t a pre-defined list of baby development red flags. Your baby will develop at their pace. So, if you don’t see them reaching any of the physical, cognitive, social or language milestones in the first few months, we suggest you to be patient. However, it is best to check with your doctor if you notice something seriously odd with your baby.
