Assalamu alaykum,
A lot has been written about taming the temper tantrums in toddlers/preschoolers. Today I wanted to share an eBook written on this subject by a Muslim mother/grandmother. MashaAllah this book has lots of beneficial advice and is written from an Islamic perspective, I would recommend every parent to read the book.
