Here are a couple of two-month milestones:
👶 You may see your newborn smile at you in the first few weeks of life, but typically that is related to them passing gas. That being said, you want to look for intentional smiling as a result of an interaction between you and your baby.
If you don't notice your baby smiling by your two month check up, this is something you should discuss with your pediatrician. ⠀⠀⠀⠀⠀⠀⠀⠀⠀
👶 At this point, you want to see your baby trying to reach and grab things (see the picture with her arm out) that’s why the play gym is a popular item at this age. It does not need to be overstimulating but something that has different textures and colors (so it can make various noises like rattling and crunching).
I encourage parents to have babies on their back while you interact with them (in addition to tummy time). I like to stand on one side of the baby and then walk to the other side of the baby while you keep talking and watch their head rotate toward the sound of your voice. Don't worry if this doesn't happen every single time.
