We had DS in the shower from about 2 weeks. It was just so handy to put him in with DH (I couldnt do it!! He was too slippery and I was terrified that I would drop him!)
Hehehe same here, with DS1 he was abt 2months, told DH he had to do it coz I was too scared of the slippery factor!! With DS2 he was abt 4wks - he's a high risk for urinary tract infections and paediatric surgeon told us baths pose a higher risk for infection (for boys, not sure abt girls). So he strictly has showers only, again with DH! Took DS2 once and I didn't move the whole time, DS2 came out just as grotty as when he went in.
