Sensory tunnel for infants. Two boxes taped together plus whatever you have on hand. I had sandpaper, feather boa, ribbon, rabbit fur (hobby lobby), reflective paper, tactile paper, fabrics, etc. Good fun for little movers. Use a hot glue gun through out to also create more tactile experiences.
I have a tide bottle and an almond milk bottle just waiting to be cut! I might also make my older guy (2.5yrs) a "car" for his small stuffed animals with one. Simple, but really fun. I made a barbie car with a tide bottle when I was a tween, it was so cool.
How To Massage Your Baby: Baby is constantly building muscle and just like us that makes them sore. I would consider setting a massage setting as well this with some lavender essential oils to smell and candle lit. Maybe right after a warm bath and get baby relaxed for sleep.
