My 19 month old ds has just had chicken pox (was quite poorly with it) and during and since then has become extremely clingy and very upset at night, only falling asleep when he's held, and waking several times in the night. Has always been confident and out going, and never has really needed any reassurance from me in day to day situations. Now he follows me around the house wanting to be picked up and held alot of the time. Daytime I can cope with but nights are a different kettle of fish! In your experiences, can this happen after illnesses, or is it just commonplace in children around this age? Nothing has happened in our home life that may have stressed him out, and his routines remain the same. Any opinions would be great to hear.
