Welcome Hatty, if you have a look at the pics of the lovely Miss Lea you'll see that she is sitting in a Tripp-Trapp while painting the dining table with blueberries, so if you like that model then of course you can get it again. Personally I would have Babybear sitting up with us at the table more often (she loves it when we are out) but we are too neutrally soft furnished to risk it... maybe one day when we get a separate living room and dining room. But to answer your question, I really don't think that a tray is essential for baby led weaning, so long as you are prepared for the mess. (And presumably with a 2-year-old you are). Your breastfeeding 'schedule-ish' sounds fine to me, but I definitely wouldn't stress too much about structure right now if she's only 6 months old. In fact, I wouldn't even stress yet if she's not eaten a thing. My baby is 8 months now and she is probably dropping a feed in the afternoon because she is eating more during the day, but it took a while and even now if she isn't in the mood for food she'll take more milk. Hopefully a more expert breastfeeder will be along soon (I only managed to mix feed for 17 weeks) but in the meantime I would advise trying to go with the flow and trust your instincts, I'm sure they've served you well so far.
