7mo DD will not lie still on her changing mat. She rolls over and tries to crawl away, and cries when I keep putting her back on her back. I can cope when it's just a wet nappy, but I just changed a horrific pooey nappy and it took about 20mins, half a pack of wipes, and I had to change all her clothes afterwards and burn disinfect the entire changing mat. Seriously, poo trailed everywhere.
Does anyone have any tricks or advice, or will she grow out of this? I'm not sure I can do this every day.
