Bed sharing and struggling bbt

Hi all

I was wondering if you are experiencing struggles with toddler

I typically keep my bbt next to me and chart off upon waking

However my toddler has dismantled one and thrown away the other

I am on my third! So busy hiding it cannot remember upon waking that I haven’t left it near me before sleeping

Urh mom frustration

Btw. He is toilet training so ruined his bed and has currently moved in with us lol

Never had a problem with it
