The only thing I could suggest is Jamaican castor oil. It helps me growth and hydrating hair. You would have to do research on if it’s okay for your baby. I didn’t put anything in my sons hair and it grew just fine.

Most babies and toddlers have thin hair. I know my girls did. Then when they got three or so it got super thick.

@abjones8888, well I use it on my hair 🤷🏼‍♀️ not much you can use on a 5 month old babies hair.

@damn.it.red, ive had people tell me to use coconut oil an then I’ve had people tell me that it don’t work not to use it

Coconut oil. Massage it into her scalp.
