A family friend attempted to buy the egg as a gift, when they were refused.
Eventually the store in Bury compromised and allowed the child to have his full name Rooney Scholes iced onto the egg.
His mother, Jo-anne – who is an avid Manchester United fan – described the decision as “madness”.
Mrs Scholes, of Rochdale, said: “It’s just pathetic that they wouldn’t let a child have his name on an Easter egg for fear of upsetting Wayne Rooney. I can’t imagine Wayne Rooney would care less.
“It’s just nonsense anyway. Rooney is his name; does that mean he’s not allowed to have his name on anything because he shares it with a famous footballer?
“It’s really annoying because it turned what was meant to be a nice, personal gift into something which looked really impersonal and just a bit silly really.”
Mrs Scholes – who coincidentally shares the surname of Old Trafford legend Paul Scholes – has a tattoo of former French striker Eric Cantona on her arm. She also has two cats, named Cantona and Berbatov, the latter named after the Bulgarian striker, Dimitar Berbatov, who Manchester United sold in 2012.
Coincidentally, Mrs Scholes has a 16-year-old son called Anderson, but he was named long before the arrival of his Brazilian namesake: footballer, Anderson Luís de Abreu Oliveira, who arrived at Old Trafford in 2007, but is now on loan at Italian side, Fiorentina.
Mrs Scholes called her son Rooney in tribute to the club’s 214-goal striker.
“He’s been my favourite player for years just because of his style of play and the way he carries the team.
“I had a couple of nervy moments when it looked like Wayne might be off to Chelsea in the summer but thankfully he stayed where he belongs.”
