Upgraded Toddler Bed to Twin Bed

Wanted to post here for anyone debating whether or not to move their 4 year old to a twin bed from a toddler bed. Even though my 4yo technically fit her toddler bed, she always seemed to wiggle down, turn sideways, and shift all over the place. Between her pillow and all her stuffed animals it was crowded but we thought she was sleeping fine.

We were moving things around in her room and so decided to make the leap to a big kid bed from her Nestig toddler bed and now she barely moves! I was nervous about her falling out of her bed without a guard rail but it seems like all her movement before was a way for her to get comfortable in her smaller bed. She barely moves now. So happy we made the jump even though nothing "seemed wrong" before. Hopefully this helps someone!
