You lot made me smile!
I did take him out - took 3 changes of clothes for him, and one for me, along with a full pack of wet wipes, and 9 nappies (can't stand a wet nappy, this one).
He became increasingly more fractious as the day wore on, and he decided to have a nursing strike for a few hours. Yay. Ow.
Eventually he decided that he did, in fact, want to feed, so I settled down in a quiet corner of the museum to do so. I was enjoying the relief and watching a pack of brownies go past when I heard grunting - dc was really giving it some welly!
So I found myself, boob hanging out (under baby), needing to change him before seepage proper started, but unable to lie him down immediately to either put my boob away or change him because it would result in a vomit fest.
I eventually managed to make myself decent and get outside to a disused bus shelter to change him. Bit soon after the feed, but it was a risk that needed to be taken. Oh dear god the stench.
But he didn't throw up!
Popped him in the buggy to walk back to the entrance, and within three minutes, the vomitfest happened. He took out his entire outfit and my top /jeans and puked so much into the buggy that it had to be tipped up to empty it, and when I'd whipped him out to hold him over so he didn't choke, he carried on vomiting and managed to get my shoes as well.
Boy has skills!
Bathed him when we got home - hopefully at some point this evening, he may leave me alone for long enough so I can have a shower.
