I've lost my phone for about a month can you help guess where it is?

If a answer is correct i will mark it a five star. My phone has been missing for about a month. Not in my room because we just reorganized the whole room to get me a whole new bed and decided to move stuff around. Its an iPhone 6 not in a bulky case. Other then my room there's my grandmas room ( probably not in there ;-; ) the living room ( where i lost my phone but we have searched the couch and can't see it or feel it ) the dining room, kitchen, and my moms room ( we didn't reorganize her room just added a new bed). I'm desperate here i have been phone-less for about a month just on my computer. Do you know what to do when your baby brother is watching a baby show and you have nothing to do but bring your bulky computer there?
