Hello Dr. Today my baby has completed 5 months. For the last 2 days I am noticing that she is moving her mouth like chewing something.... and then I checked her mouth there's nothing. I feel like she is practicing eating(or having some foods like) when we eat foods front of her she continuously stare and try to move her mouth like chewing something.. Can I start liquid cereal 🥣 right now or should I wait till 6 month complete? she's totally on my breast milk.
