I am step father to a seven-year-old boy (let's call him H). H's father is very much involved in his life. He sees him every night for a couple of hours and they (Mother and Father) alternate weekends.
For a long time now, probably 3 to 4 years, H makes very loud and daft noises. As a baby this was looked upon as "he's just a baby", however as he starts to mature we (the Mother and I) were wondering if there was anything we could do to help him reduce these outburst of random noises and acts of silliness.
To try and give an example, we would all be sat watching TV or busy in the kitchen making dinner and randomly H would make daft noises like "boop, beep, ba, bottom" to himself and in no way related to what was happening at that time. It's not like he is mimicking something on TV or trying to get our attention. He also has a tendency to slap his own bottom (his Father did this whilst play fighting when he was younger and sometimes still does). It's not a problem in that context but he has what I would call an obsession to do it to himself and it can be quite embarrassing when we are out in public and we are having to tell him to stop it.
On top of this my girlfriend and I have recently had a baby (he is now around 11 weeks old) and what we don't want is for our newborn to mimic this kind of behaviour as they grow up.
It does sound like I'm quite strict and I don't want it to come along like we are trying to stop our child from being a child. The noises are all the time. Personally I feel it is stopping him from focusing on tasks at hand and his ability to concentrate.
How can I look at stopping our son from making random, silly noises and generally acting daft?
