I'm feeling pretty fed up with myself at the moment? 
DD is 3 is an absolute delight most of the time, but when she has a meltdown she has a major one! This has been recently witnessed by two of my closest friends and I feel embarrassed with how I handled it?
DD goes to my parents two days a week, with me all day on one and nursery for two days, she no longer sleeps in the day and is absolutely shattered when she gets home. She is a very poor eater, so thats a battle, she is usually good at going to bed.
So these are the two scenarios, comes to bedtime and she doesn't want to go, she has a complete tantrum and refuses to put PJ's on, wedges herself in between her bed and wall and I literally couldn't do anything with her, my friend is watching all this and I'm nearly in tears. DD starts kicking out at me as I try to put her PJ's on, friend said she would smack her for that, I don't smack her, never have. We both literally had to force her to have her PJ's on and she was hysterical, I left her in her bedroom and she cried herself to sleep? 
Last night, we both went for a sleepover at my other friends, friend takes her daughter and mine to bed all was going well until she decided she didn't want to go to sleep. She got herself in such a state, she was hysterical and seemed to be terrified of me
, neither of us could do anything with her. She cried herself to sleep again. She gets so upset that she spits on the floor with temper! I was so embarrassed and didn't know what to do?
This friend says she runs rings around me and I give in to her, but I don't think I do?? She also believes in smacking? So what would you have done in this situation as both tantrums went on for at least half an hour? As soon as she starts she wants her Daddy, he lives 280 miles away and she never plays him up, just me??
I'm at my wits end with her tantrums, I'm starting a new full time job in three weeks and to be honest I'm dreading how she is going to be, I didn't want to go back FT but needed to get a job closer to home (1 hour drive at the mo, so needed to take it. I feel like I should be doing more to stop her but what?
Any suggestions please
