Anyone used a myhummy for a 2 year old? My lb is struggling to self soothe since I've taken his dummy away. This include middle of night waking and very early morning wake ups. I know white noise is usually for babies so wondered if would work on my 2 year old. Also thought if I got the teddy maybe he would become attached to it to replace the dummy which is why I'm not using any apps on my phone etc x
