Woolly or silky, there are lots of different types of scarves and they come in handy for pretend play and fun with your baby.
A scarf makes a brilliant tickly snake. This shows your baby you can have fun with objects and pretend they're different things. Make a snake sound while you play.
Try hiding behind the scarf and then popping out for a game of peek-a-boo! This shows your baby that you're still there even when they can't see you.
You could make up a song as you wave the scarf. A silly song might make your baby giggle, or try a slow song to get them ready for some calm time.
