Hi MD, sorry i posted just before your last...

we used to swaddle leila as well (doing the half one) but i found that it distracted her too much. and then when she became really mobile the act of turning herself over while she was sleeping would wake her too much. and she started the midnight shennanigans, so then i moved to sleep suits and against all MACH nurse advice I put her on her belly (she would roll over on her own anyway, so figured i would save her the bother). it seemed to really work with her...
but yeah, you're right it's probably just recovery from the teething upsets...i found that leila took ages to recover from the wedding stuff.
