Really odd problem, and not sure where else to post. DH is wonderful, kind and caring but this problem is really bothering me. For background, we're together 7 years, married for 2, DD is 7 months old. He's great with her, in a senior, responsible role at work and is articulate, thoughtful and great fun.
This problem is long term, but probably bothers me more because I'm on maternity leave and sometimes deprived of adult company! He often makes odd noises instead of communicating properly, just with me. Like if I tell him about my day, he might say 'That is the flumblewormp of papunosity'. If I offer him a cup of tea, he might answer with 'that's what she said' instead of an appropriate response. Instead of informing me he needs to use the restroom, he might flail his arms and legs and shout 'wee wee wee wee'. This can be constant on a bad day, a few times an hour on a good day.
He manages to stop this completely to talk to absolutely everyone else. He seems to find himself really amusing. When I ask him to stop he tells me he'll 'be a good boy', and whenever I've tried to discuss it seriously he seems positively dejected.
I'm worried about its impact on DD learning to talk in the near future. I often feel dismissed and almost as though I'm the one being silly? He's otherwise such a lovely person.
There are no likely mental health issues. I'm a psychiatrist. There's no pervasive low mood, no delusions, no elation. No likely obsessive/compulsive element. I've recommended asking his GP or possibly seeking an opinion from someone who isn't his wife, but he's too embarrassed and can totally stop when in company.
Lost. Help!
