Does anyone know of an appropriate book for 1.5 old that has a theme of mommy leaving but coming back. Recently my daughter is going through separation anxiety any time I need to run a quick errand and can’t bring her. I never ‘sneak out’ I always tell her mommy will be back (x,y,z). I only leave her with her dad so it’s not a stranger issue. she absolutely loves to read so a book would be best but even a show that helps them understand the concept might be another option. Thank you
