I know exactly how you feel. I'm also having problems with SA at the moment. DD will go down for naps, but wakes soon afterwards, lifts herself up and if she can't see anyone, starts crying - the moment someone walks in, she's all smiles again. At night, she wakes up, lifts herself up to a sitting position so she can look around, sees me right next to her and then goes back to sleep. She will also roll over in bed (yes, she sleeps with me ... naughty mommy
), reach for me, cling onto me for dear life and then go back to sleep.
I actually thought she was getting better because she has never cried when i leave for work, however, i had to eat my words this morning when she started crying when i left for work - i was heartbroken and it took everything i had not to rush back, grab her and cuddle her - i carried on walking, got in my car and drove away - i thought i would just die, leaving her there crying for me.
Anyway, like everything with babies, i know this is just a phase she's going through and i can only reassure her that i'll be back and that everything will be ok whilst i'm gone.
