In literacy we have been learning about possessive apostrophes. We found out that we only need to place them if it belongs to someone/something  and should NEVER put an apostrophe  beside a plural word

eg.

I hope the “dog’s” bark will not wake the neighbour’s baby although the baby might already be awake.

I can’t remember the “song’s”name just now but I am sure it will come soon.
