Shelley, what are you most concerned about, is it the quantity dd is eating? Some los don't even start to have solids until over 7 months, and then their appetites vary enormously and can be affected by mood, illness, tiredness, distraction.
Do you have dd eat with you? I found that it helped enormously to not think of introducing solid foods as part of Eat but rather of Activity. So Eryn kept her 4 hourly Eat pattern with her milk feeds, and then just practiced with solid foods when we ate our meals. Even if she didn't manage to swallow much, she got the idea of sitting at the table as a family, and was able to watch how we did things.
If the gagging really scares you, perhaps you could go on one of those free local child first aid courses, your health visitor should be able to advise on one, and then you might feel more confident with what to do if dd does choke - but also remember that gagging and choking are different, choking is when a foreign object (like food) enters the windpipe and so you can't breathe, whereas gagging is what you do when you need to move a piece of food from the back of the mouth to the front - it looks and sounds more scary than it is, and is a useful skill for dd to have!
BLW can help the process, babies are actually less likely to gag or choke if they self-feed because they have control over what goes in, and offering big sticks also helps this, because they only bite off a bit, rather than picking up a chunk and stuffing it all in and it being too much!
HTH a bit?
