Hoti - I am so proud of my harnessing efforts We had this harness that we got in a target bounty bag for free, it was one of those walking ones and it was in the cupboard unused. I just took off the lead part and was left with the bit that goes around their shoulders and clips up at the back. I also had these other 2 bits coming from that on either side of her back which I looped through the slats in the bottom of the high chair and did them up. The shoulder part actually detaches totally from the 2 lead parts. So I just put her in the shoulder part, then put her in the high chair and click one side of the shoulder part into the lead part that goes through the slats. She's too big to click the other side because the straps aren't long enough but it seems to keep her contained. I am looking for a 5 point harness that I will be able to wrangle somehow. What I found is that it's not that she needs to be secured against the backrest and I'd prefer her to be able to reach for her food/water anyway, it's just that she needs that downward pressure on her shoulders to remind her to sit when she tries to stand.
