Started solids and tummy aches

So dd has recently street solids (6.5months) after a couple of weeks of trying some puree on a spoon with no luck we have just gone the BLS track. She LOVES it. Attacks her food with relish, is having so much fun tasting everything and has a ball sitting with us at meals. It is working so well except for one thing. We are having an awful time at night. She groans, she wimpers, she farts and then sighs. She's up every hour of the night were previously she slept 8-10hrs straight at night. She is just so unsettled. She's started pooing like 3 times a day, where it used to be once every 2 days. It started when she started the BLS, last night was the worst, but I've been on ab's the last 2 days so I think that's helping the problem. I don't know what to do, it's like her tummy is not coping with the onslaught. But she loves it. She gets excited when I start to set the table. Should I just ride it out. Hope it settles down in time??

What has she been eating so far?

Fruit - apples, pear (she just sucks on them) strawberries, rockmelon (she manages to eat little bits of them) watermelon ( eats quite a lot of that)

Toasted bread and rice cakes spread with avo or hummus or even some puree.

Veges - pumpkin and potato (just smooshes then really) broccoli, carrot, cucumber, (she has a good go at them)

Cheese once or twice

And she had a little bit of chicken when we had chicken the other night and she gnawed on a bit of rissole last night when we had that for dinner.

Am I introducing her to, too much to soon. I've just been giving her little bits of whatever we have been eating.

Antibiotics could very well account for the upset tummy. Maybe see how it goes once those are finished. The poos will also change once they start solids, so that may be normal.
If you're concerned maybe just wind back what your'e offering her a bit and see if it makes a difference
