I my baby boy is of 26months. he often faces problem in having proper sleep. first of all he struggles a lot to fall asleep and secondly he keeps waking up in half and hour or such whole night. I thought it might be teething period, it might be gas, it might be wet diaper, it might be over tiredness, everything possible. but now I am actually worried. any cause can't be this long. or if it is a permanent issue then there must some solution to it. please suggest some.
