WG I'm very sorry to hear you have sleeping problems again. As others have said, this will pass and I doubt its anything you are doing, DS1 and DS2 are so different and I honestly havent handled it any differently.
I used to want to throw DS1 out the window too. Just to get him to be quiet for a bit. One of my friends also said she wanted to push her baby into a canal and go home and go to bed when she was out on a walk once too. I think these are normal feelings if not nice ones - we have to have some outlet and way to cope with the constant demands, we wouldnt be human otherwise. The fantasy at 4am is the safe way.
I have nothing else to add to what anyone else has said except to say that is it worth getting her checked out at the GP ? I only say this because DS1 went through a phase of very similar sleeping to what you describe once and in desparation I went to the doctor and it turned out he had an ear infection and the doc reckoned its unpleasant for them to be lying down when they have them, and they feel pretty rotten, hence the frequent wakings and general unhappiness at night, as THEY cant sleep even though they want to. DS1 had ear infections quite regularly.
I feel for you (and Veggie) with home stresses too. We have also had those with bereavements and DHs work stresses, its very hard. Dont be too hard on yourselves, our children are too young to remember if some days we are merely coping, and arent the parents we would like to be. The only way I have taken to deal with it is to take 30 mins for myself every so often and also try to be nice to DH, as sadly he gets the brunt of any anger/resentment or stress I am feeling and vice versa. When W had one of his nursery visits I was able to sit in the grounds of my work for an hour and not have to do anything. This was when I felt able to think about and shed some tears for the sad things that have happened recently. It really feels like there was no time until then. I hope that you can get into a bath, get out for a walk and just get some clear headspace.
TBH when DS1 was 6-7 months old I could not believe anyone would want to do it again, I was having such a bad time, and part of the reason I had DSs as close as I could was to get it all over with. It will get better and in the end it didnt put me off.
Blumming heck, long post. I just really feel for you WG as I remember how that felt, I really do. Every weekend I was desparate for just a bit of my old life back.
Hi to everyone else ! Thanks for your formual tips, I am going to try a variety of cartons next week, given he has never refused any concoction I have given him I'm sure I can find something he will drink...
On the developmental side, DS2 can roll, but doesnt much. He can sit for quite a few mins on his own, but has to be watched as he may fall over. He doesnt crawl, pull himself up on things, or anything like that. He has bumpy gums and no teeth. HBut he is a lovely laidback dude Most of the time he is fighting off his loving but a bit heavy handed big brother..
