Our two year old GD went to the zoo with a friend (pre-arranged) and by the time she came home at 5, DD was back home, sitting having a cup of tea, and GD had had such a lovely day out, sat on DDs knee telling her everything she had seen, and it was some minutes before she noticed Nanny & Granpop were visiting, and what's more Nanny was holding a baby! Baby was born in hospital whilst we were on motorway, driving up from Devon to Leics, so we didn't have time to take over as was planned, but it really couldn't have been better. We felt afterwards that it was lovely that she got a big cuddle from DD before she was introduced to baby, oh and the baby had brought a present with her for GD (only small, but much wished for)
Lack of public toilets in towns.
