Just the two for me - one of each flavour - aged nearly 4 and 1yr old. Don't know how anyone copes with more than two - our first wasn't too bad but our latest addition drives us mad - mainly because she screams her way through most mealtimes!! Wouldn't be without either of them though!
I wouldn't say we wont have more, but just not for the foreseeable future!!
I have a Nigerian customer who has SIX aged from 16 to 3. They drive him mad and cost a fortune (£43,000 for air tickets for his family's latest UK/US holiday) and he can't stop because he's a left-footer and completely obedient to the Pope. No wonder he suffers with stress.
