Nathan's favourite game is mummy and daddy. He loves humpty dumpty (throws himself backwards by planting feet in your stomach at just the right time ), flying above daddy, this old man, row row the boat, you lying down then him sitting on your chest chatting away, him crawling over you,clap your hands everyone together - stand up- sit down. Reverse peekaboo, where nathan does the peekabooing (for real - it is hilarious, he dives behind my shoulder to beam at however is next to me, then dives back and repeats endlessly). Shredding magazines and crumpling newspapers. Also this is still a hit.
Lilyloo, it is a lot smaller, but this is a real hit. The sounds the thing makes are insane though, Nathan quickly learned to kick it then kicked everything else to see what sound it made (including me )
Re camping, you may actually find they sleep better (as long as they are warm) as the fresh air knocks them out.
