Child friendly attractions and stain removal

Although Jack-Jack still isn't walking he's extremely active and mobile, crawling at the speed of light in every direction, standing up and walking holding onto furniture/hands and wanting to investigate absolutely everything. Andy is walking, but is still a bit wobbly and can't walk very far yet. We're always on the lookout for new places to go where they can safely let off steam and have lots to investigate, but which doesn't require children to be able to walk (or not to put things in their mouths, which rules out things like petting farms at the moment as Jack-Jack doesn't want to stay in the buggy or carrier!)

We've been to two local museums lately, neither of which are specifically designed for children, but the experiences at each were so different! At the first, an employee rushed over to help us, told us where to leave our buggy and looked really pleased that we'd brought young children with us. Many of the exhibits were low down and the floors were clean, so we were very happy for Jack-Jack to crawl around and discover everything with us - there were doors at the entrance to each room so we knew he couldn't get out. He absolutely loved it. At the second museum, we struggled in with the buggy and had to find somewhere to put it, whilst being frowned at by staff and visitors when the boys made a bit of noise. The whole museum was open plan (including the staircases) so we had to be on our guard at all times, chasing them around trying to keep them both safe and in view - it must have felt to them like we were spoiling their fun and Andy particularly got quite frustrated that he couldn't go wherever he wanted. Many of the exhibits were high up so we had to lift the boys up to see anything - from their level it must have looked quite boring. The whole experience was quite stressful and we didn't stay long. We'll definitely go back to the first museum on a regular basis, but I think we'll think twice before attempting the second with young toddlers again! It was an interesting attraction for adults and older children, but it's amazing how just a few little changes could really widen the target age range considerably.

I've spent the last week trying various methods to get a large unidentified stain out of the front of one of the t-shirts that Jack-Jack's mum bought him. He came back from contact with food down his front as his mum had chosen not to put a bib on him, and I'm now stuck between a rock and a hard place, because if I send him to contact in a stained top it will all be my fault and I've stained it on purpose, but if I send him in a different top it's a personal attack on mum and I'm saying the clothes she's bought him aren't good enough. It's almost funny, I've bought a specialised stain devils product as a last ditch attempt to remove the stain, which cost about the same as a new t-shirt. If we had a local branch of the shop the t-shirt came from, I would probably have gone out and bought an identical one to save any hassle!
