We've been invited for a long weekend abroad(4 nights) by some old friends whom we have been on holiday with pre-children but now don't see very often as we have moved.They have a DD aged 13 months and my 2 DSs are 2 and 5 months.We would all be staying in the same apartment which is owned by her parents and is luxuriously furnished with lots of lovely things.My 2 year old has been a handful since his brother was born,often scratches other children , pulls their hair, and also runs off and doesn't stop doing things when asked.He is fine in toddler friendly spaces but has a tendency to pick up everything in sight and turn every knob he can find.I'm worried about him damaging our friend's flat and also about him constantly upsetting their daughter( he scratched her twice at a short visit to their house last week).With a baby to look after too, I can't always control him, even with DH around.I am worried that it won't be much of a holiday for anyone and have looked into keeping our flights which are already booked but staying somewhere else, but at the time we are going it is hard to find anything affordable nearby so I am thinking we should just cancel the whole thing.I have raised my concerns with our friends and they said they are not worried at all,and that we will all have to help keep an eye on DS1 and are looking forward to the holiday.I can't help but think they don't realise what toddlers can be like as their DS is not walking yet.AIBU to want to not go?WWYD?
