My DS is 11 weeks old now and in the last few weeks we have managed to sort his sleep out by swaddling him. If he isn't swaddled then either his moro reflex wakes him or his arms and legs flail about and he can't settle. With swaddling I can pop him down awake and he'll self settle most of the time.
I read something that said you should stop swaddling at about 14 weeks. Is this right? If it is, why? Will it do him any harm if I swaddle him until his reflex is less strong and he can control his limbs a bit better?
