I can't work out if I am being a bit silly or not so am biting the bullet and asking the MN jury...
My sister and her boyfriend have a lovely 6 month old son and are off this weekend to Centreparcs, but leaving the baby with his grandmother. This is, that I know of, the fifth time they have left him with someone for the weekend, which considering he is 6 months old, seems a lot to me. When I heard they were off to Centreparcs, which is very child friendly (although I do realise the baby is too young for most of it), I actually felt quite sorry for him. My sister said they 'need a break' as they have both been working long hours (and the baby has been farmed out to various grandparents) and taking the baby wouldn't be very relaxing.
So, is it me being unreasonable to think they are being a bit out of order, or is their behaviour perfectly understandable and normal...?
