super scary... help?

ok.. so i already talked to the night nurse and she just said to keep an eye on 5 month dd... so about 15 mins ago she was playing on the floor and i could tell she was getting super tired. so i picked her up... her head just kind of flopped down. she would pick it up then flop it down again., she had color and was breathing and acting fine... except she didnt want to pick her head up much.i moved her around because i had never seen her do this and it scared me... well then she started vomiting! it had been over an hour since she had eaten. the night time nurse thinks she was just really tired... well i put her in her swing after she stopped puking... she was smiling, and her self again... then fell right asleep and has been out cold. SO thinks she was super tired (she didnt sleep well last night because of teeth) and when she flopped her head she gagged her self and threw up from it?!

maybe she has a virus, poor baby. Keep her hydrated mama.

She may have had an upset tummy and that was all she needed was to get it up. I hope she's better, poor baby.
