Ok so this may be a bit of a rant - sorry!
Ds 21 mths was just now having a tantrum about something trivial, the tantrum was pretty mild, just a bit of loud whinging and a few tears really. She's a good girl and doesn't tantrum much and when she does they're soon over and forgotten about. I tend to just let her get on with it and get it out of her system, then give her a cuddle when she's calmed down. Anyway dh really shouted at her, then when she carried on worse he said "if you don't stop you're going to bed" at which point she had a complete meltdown, so he carried her upstairs and tried to put her in bed, I could hear her screaming hysterically and calling for me, her screaming and crying just went on and on. I was trying to let him deal with it and not interfere as I do think we should not undermine each other. but I was so upset about his go to bed comment as I don't want bed to become a punishment, she loves her bed! she's a wonderful sleeper and still having a lunchtime nap - I just really don't want her to start seeing it as a bad place. Also it was upsetting me how much of a state she was getting herself into. So I went up and she came running over for a cuddle - I tried not to talk about it in front of her, just said can we talk about it later. But dh now furious, accusing me of nagging and interfering - and refusing to discuss it as he says I'll just criticise him.
What do you think?! I really don't want to undermine him but then his discipline techniques are really rubbish!! and she's such a good girl, we really don't have any problem with her so obviously my techniques are working!!
