DS is 11 weeks and loves being sat up (supported by us) on the settee, or sitting up on our knees facing forwards. He seems to much prefer it to being in his bouncy chair. I have looked online and seen a 'bumbo' which is a seat suitable from 3 months old. It looks just like a potty though which is putting me off a little, silly as that sounds! Are there any alternatives to a bumbo to help a baby who would like to sit up?
TIA
