When the item was aired on January 10 this year viewers were told that the stunt was safe because the baby was a doctor's child. The presenter went on to encourage viewers to "do it on your brothers and sisters as it's very, very funny".
In upholding two complaints from viewers Ofcom ruled that the item was in breach of programme codes of conduct relating to children and imitative behaviour.
In its ruling Ofcom said: "We were particularly concerned that a presenter of a children's programme should encourage children to feed a baby at all.
"We also felt that there could be a risk of children imitating the stunt with more harmful substances."
Carlton, which makes the programme, has defended the item saying that it was handled responsibly and that older children were unlikely to be influenced to give young children anything that might be harmful.
Meanwhile Ofcom also upheld complaints from nine viewers about swearing and sexual references on 'Osbournes' spin-off show 'Union Jack', which was broadcast on Channel 4 on Sunday afternoons earlier this year. The complaints specifically related to an interview with Marilyn Manson and an item where Sharon Osbourne appeared to say "fuck off".
