I Think My Dead Grandmother Is Haunting Us!

Just for reference the ages in this story are from the time this happened, not current ages. This started when me (30F), my husband (31M), my sister-in-law (26F), her husband (25M), and my mother (52F) and father-in-law (57M), had gone on a trip to the Gold Coast while we were all off work for Christmas.

We were staying together in different rooms of an air BNB, at this time I was the only one with a kid, my 1-year-old daughter who came with us. At around 9pm I said goodnight to everyone and went to bed but woke up at around 1 in the morning and saw my door slowly opening, a figure with a hat on walked into the room, at the time I thought it was my father-in-law, I nudged my husband and he woke up but didn't move, the shadow figure slowly moved over to my baby's cot and peered over the edge before disappearing.

That morning when my husband woke up he told me he would ask my father-in-law if he was in our room last night but he wasn't. I didn't think much about this until I got a phone call from my mother telling me that last night at 11:50 pm my grandmother had passed. I think this could have been her checking up on us but what do you guys think?

Lucky I didn't finish writing this because I was talking to my daughter who's birthday it was yesterday and she was telling me about a lady that visits her every one of her birthdays, I think this could be my grandmother, but maybe it's just her imagination? It seems like too much of a coincidence to me to be fake and I'll update this if anything else happens.
