I like you scones and you are not being self pitying.
Motherhood is hard. It doesn't tell you that in paremting books (or pregnancy test kits), but it is an inexorable truth. Let nobody tell you otherwise. It is also very easy to get so caught up in the drudge of it all - disturbed sleep, not ever being able to eat a meal without having to attend to someone, alwyas having baby detritus on your clothes etc - that it is all too easy to let that overtake your impression of motherhood, and forget the smiles and giggles and nice stuff. After all, it is not dissimilar to focusing on the one person who gives you an appraising look when many other people have commented on how nice you look. But do try and remember the good stuff - how about trying to write down three nice things that happened that day as you go to bed? It may just start to turn your mind from pessimism to optimism.
Have you talked to someone in RL about how you are feeling? If not, please do. Your DH may not be enthralled with his job, but that doesn't mean that he won't empathise with how you are feeling and your desire to escape. Do you have any childcare in place for either of your DDs? Going from two to one every now and then is a massive relief for me, and maybe you would feel the same. If your DH is not the listening type, have you a friend you could talk to? A sister? If things are very bad, please do go to your GP. You have had two babies in a short space of time, and PND is a possibility.
Try not to fret about your Dad. In time, this will feel very minor, but he probably just wanted you there for him and not having to look after your DDs at the funeral. It will pass. He is caught up in grief at the moment. Try not to stress about it when you also have to get through the funeral - I am sure he will realise in time that you had no choice but to take the DDs with you and that this was not the easiest thing for you to do.
CP you be kind to yourself as well. It sounds as though you have had a bad run of illness recently. Hope you feel stronger soon and things get easier.
IC glad your new firm approach is working for you with DD, and bear that you are finding a way with your DS. Like SB, I have started a reward chart with DD2 - they are definitely at a tricky age!
NK don't feel guilty about your mum looking after your DDs. Try and relax into it and enjoy it (easier said than done, I know, I always feel guilty if someone else has my DDs so work or do chores rather than relax).
mous what did you decide about your DD2 and the Tictacs. I am in agreement with most that a late punishment won't work, but a rollocking for your DH is most definitely in order!
