My 8 month old is constantly whining and it is really starting to get me down. I know he is teething (we also have much drooling and biting- he has the bottom two teeth but I think there must be more on the way) and he has also had a cold lately and he's trying to crawl and all of this is very frustrating for him. He has started waking in the nights again for milk and just being a general grump. So knackered!! We're thinking of trying to teach him a few signs so that maybe he can communicate his needs during the day at least. Anyone else do this? I'm thinking a handful of simple signs like 'more food' or 'milk'. Would love any suggestions/advice. Thanks!
