Hello, so I’ve spoken to a doctor regarding this. Bean husk can be used from newborn and only to use when baby is under supervision (napping in the day, etc). At night, there should be nothing in the cot and if baby is swaddle, they won’t have that startle reflex too. For Baa Baa, it is recommended to only give baby after 6 months as it contains micro fibres and newborn’s lungs are not as developed so breathing in these micro fibres are not good for them. Hope this helps!
