Baby led weaning

Okay my sons 6 months, will be 7 on the 16th. We’ve been giving him purées since a few days before he turned 5 months. He has breakfast and tea everyday.

So when he turned 6 months I wanted to try baby led weaning. We started off with broccoli and he hated it, guessing he didn’t like the textures in his mouth. So then we decided to try him with chunkier purées. He’s been fine with some of them but he did gag at one point. We also give him melty sticks which he picks up himself and and eats himself.

I am really really nervous when it comes to him eating food. He put a bit too much in his mouth and I freaked out and started shouting for my partner to come in. I’m a ftm and I am really struggling with him eating whole foods. I’ve watched endless videos of babies gagging and chocking and what to do. We don’t have a first aid baby class in my area so I can’t do that!!!

My partner was saying if I freak out baby won’t want to eat. I know I shouldn’t but I get really scared. I can’t even sit with him when he’s having whole foods I have to go out the room and let me partner do it bevause I’m so nervous

Please help, how do I over come this
