Can I feed my baby at 5 months?

Rina
Okay... So my little boy is turning 5 months next week... And lately (actually its been a month and a half now), he keeps grabbing at food. Juices, junk foods, drinks in bottles, spoons...anything that has food in it basically. I was wondering if any of you started feeding your babies earlier than 6 months? I want to know why you decided on it and did anything 'strange' happen? I'm quite undecided whether to feed him liquid-y solids when he turns 5. But I feel like I should wait. What do you guys thinks?
