Update after the first 6 nights;
First of all, little Diego has been amazing, potty training is going very well! We have run into another problem though;
We're trying to get Diego into a routine of eating, going potty, playing/training/socializing etc, sleeping. We're using a crate, which Diego likes, but he really hates being locked up in it (same in a pen). He will whine, scream and bite at the crate when locked up during the day. At night, he doesn't have a problem sleeping in the crate next to our bed. We are feeding him in the crate, playing crate games, using a Kong (which he loves for 10 seconds but loses interest after that), he's got an old T-shirt in it.
The problem we're having because of this, is that the only way we can get him to sleep or at least settle down during the day, is to have him in our lap on the sofa. We've started doing this just to help him settle down a bit after playing, so we could put him in the crate once he was asleep. This worked at first, but now he wakes up and only wants to get back to the sofa. He will just run around, jump up to the couch and bite everything. When he's in the crate, he get's really stressed so that's not helping. When he starts biting, we re-direct to chew toys, but that only works for a short time.
So for us, it's really hard to tell if this behaviour is because he's not getting enough mental/physical stimulation, or maybe he's getting too much of it. Would love to get your advice on this, and also on other ways to help him settle down a bit when he gets worked up.
