Month 4 Development

At the 4 month mark there are big shifts happening. New skills are emerging, and big changes are happening in the brain:

  • There is a huge burst in cognitive awareness and increase in motor development

  • Babies are learning to roll over, back to front, and front to back

  • Depth perception is evolving: they are learning to grasp things with their hands and to bring things to their mouth.

  • Babies are pushing up on their elbows, holding their head up in tummy time, kicking and pushing their feet

  • They start babbling, laughing and cooing

  • They are Little Explorers, using their hands to explore toys

Below you will find more on Month 4 development, Month 4 Sleep, normal sleep disruptions, samples of daily naps, and gentle tips for success during this time.
