Cot to bed transition

[Lullaby88]

Hi we are looking to transition my just turned 3 year old from a cotbed to a bed. Can anyone give us ideas on what type og bed to get/mattress? We are so confused? First we were going to buy a toddler bed with side rails.. but someone said just buy a single bed and a normal matress and put side guards up. Im so confused. Please help..

We went to a single bed with a bed guard with both kids

We had a cot bed that we converted but it didn't have a guard rail. He did fall out the first night but was fine after that.

Unless they are a real wriggler or the bed is really high then you probably don't need rails.
