You poor thing. Your MIL sounds a bit of a nightmare, to be honest. I found my PILs absolutely impossible to deal with after my DS1 was born, but it did get better as the children grew up, if that gives you any hope. For me, it didn't help that I had a sleepless baby and was suffering PND. I was also trying really hard to be a good mother - well, a perfect one, actually (took me a while to realise that wasn't possible
). My PILs seemed contemptuous of my attempts to be a good mum. I remember my FIL dismissing something I'd said about childrearing with the words, "I suppose you've been reading those flippin' experts again, haven't you?"
I was so tired, depressed and anxious that I took everything to heart. MIL was always bundling up DS in extra layers to keep him warm, whilst I was unwrapping him again and worrying about over-heating and cot death. She kept giving me clothes for the baby, but they were all things that she would have bought for her own baby in the 1960s and either not my choice or dangerous, in my opinion (little nightdresses with long ties on the necks, for instance
). For her, this grandson was her chance to relive the favourite part of her life and, looking back, it must have been hard for her to come to terms with the fact that this was not her baby, but mine.
I think that the first year or so is incredibly hard. I wish people had just been more supportive to me at the beginning, instead of criticising my choices. What I needed - and what you need - is practical, non-judgemental help. I really understand your feelings of possessiveness towards your daughter when your MIL is trying to take her over. But you really needn't worry about that. She doesn't stand a chance.
It's appalling that your MIL is criticising you via her husband. But she is the one who is going to lose out, in the end. Could your husband say anything to her when she next does it? Maybe in a light-hearted, rather than confrontational, way? It's no good your DH saying you are being 'silly'. That is incredibly unhelpful - it's belittling you and not facing up to the problems with his mum. He just wants to avoid a confrontation, doesn't he? His mum doesn't sound like the easiest person to deal with.
To return to your last question - did the feelings ever go away? Well, yes, things did get better. We moved further away, so couldn't see so much of the ILs anyway - that helped. MIL still indicated her disapproval over some of my choices (eg she hated me training as a childminder because she thought it was unfair on DS), but I became more confident and more relaxed about my choices, so I didn't bristle so much at her criticisms. Nowadays, I am much more able to see how good she can be for the boys (I have two now). She brings them presents (including too many sweets and chocolates - another on-going issue!) and she likes to spoil them. I am not a 'new mum' anymore, so she can't really tell me how to do things and act as if she is the expert. And, most importantly, even though my sons love her, there is no doubt that they really, really love me and need me more because I'm their mum. Nobody can threaten that.
I think you should distance yourself from your ILs for these precious early months. Why should your early months with your daughter be ruined by your MIL's overbearing nature and insensitivity? She is not giving you any support at all. In time, you may feel less upset by your MIL's behaviour - maybe even able to laugh at it - and then you won't mind seeing her so much. But I wouldn't do a week at Christmas again, if I were you! That was obviously too long. My own mum wouldn't stay for that long in case she outstays her welcome and I love her to bits! Two days is probably quite long enough for most visitors.
And it would help if your DH was a bit more understanding about it too, although I can understand that he feels that he is stuck in the middle.
