Too young

So my baby is 4 months I know it’s obviously too early for foods but he is starting to notice everything I do even when I drink water from a water bottle he will get excited and try and reach I feel bad eating around him

He just had his checkup and she said we can start cereal soon then 5-6 months Baby purée

I’m thinking of skipping out on cereal but he’s so excited I can’t wait honestly till he can start trying I’ll probably wait till 6 mo the just to be safe

I’ve also heard of baby led weaning not sure has anyone tried that??
