Baby snacks (Gerber puffs)

My baby turned 9 months old today & I give her the gerber lil crunchies or the gerber puffs... and i'm so scared she is always going to choke on them and never does.. I sit there and hold it while she eats it so she doesnt bite a huge chunk. Like a few minutes ago i was holding a gerber puff and she managed to get the whole thing in (didn't choke)... and my anxiety shot way beyond the roof 🥲🥲🥲.. When does the anxiety end..
