I don't call anymore, unless one of them was upset in the morning (which is pretty rare). At first I rang but not now. And I'm pretty sure the carers don't think any less of me. Really though, it's up to you. If I didn't do most of the pick ups, I'd probably ring more often just to have that contact with the carers and find out if anything in particular happened. But as Bath said, I'd probably do it later in the day as lunchtime is a bit chaotic for them.
