Activity time that is fun for both mum and baby (for those fed up cooing and singing itsy bitsy spider
)
Putting them in a bouncy seat or prop up, get a magazine YOU want to read and read aloud, with interaction. Even toty babies will answer your questions in the crossword puzzle, you just can't understand it yet.
Go on youtube or any streamer and type in the music you enjoyed as a teenager. Sing along and dance with baby.
Put them in a soft structured front carrier and go shopping, do housework, while explaining everything to baby. Make sure it's A-time, as time in a wrap counts as tummy time (thumbs up for those whose baby hate tummy time, no matter what you do). Let them feel textures as you go along.
Put the radio on the classical channel and massage or drum on baby's body to rhythm while trying to guess if this is Mozart or Vivaldi, Beethoven or Paganini. Bit of culture has never hurt anyone.
