Looked over the door this morning to find the smallest kid now with Mum. She had got out of her pen and gone in with Paddy, her dad. I thought I had all gaps secured, but she is so slender she had managed to get through at the corner. Other kid is plumper and obviously could not fit. She did it again this afternoon. Paddy is fine with the little ones, its the fact that she could get stuck that worries me. I have fitted some mesh over the gap, which both kids went up to and inspected.
They are both getting very mischievious now, and into everything.
