Trying to teach a 16 month old to play by himself is like trying to teach...I don't even know!
Until now... are you ready for a brilliant tip?? (shout out to the mom-in-law and other teachers on my husband's side of the family!)
It's called : Suggested Play
It consists of creating different "stations" throughout the rooms that you would like your toddler to play in.
Basically your toddler will just move from station to station on his/her own! And the best part is that you don't have to keep buying new toys. You can just switch up the stations every day or two.
It's working for me. Let me know how it goes for you!!
