DSIL was visiting with DN over the weekend. DN is just under 7 months and was lying on the playmat on his back and then began to strain and try to lift himself up. DP sat him up and he was quite happy as he could look around but DSIL got very annoyed with him and immediately lay DN back on his back and said they were just leaving him to "get on with things at his own pace".
He’s her child so I didn’t say anything, but surely there’s nothing wrong with holding a 7 month old with good head control in a seated position? We used to do it to DS - he was fine and could sit unaided by 7 months, which I thought was fairly common. I could understand DSIL getting annoyed if DN was only a couple of months old but I don’t think DP was doing any harm here.
Or is there some sort of dreadful consequence that I was missing?
