With a 2 year old on your own it is not a holiday... I decided after going on holiday with my DS and a relative at that age I would just do lots of day trips..It worked much better. He slept better in his own bed. I was on my own still at night but better been on my own at home and worked really well.
Can I say as they get older it gets easier. I now do them on my own with DS(8) he is better company can stay up late .. We went abroad the first time this year and thoroughly enjoyed it
