You know, I think we worry whatever our situation. At the moment I worry that M is too attached to me because she never spends time alone with anyone else. Remember in the beginning how you fretted when your DH wasn;t doing anything for TJ and you had to do everything yourself? Now look at how much he does! Wow, how things have changed. And how, in another few months' time they will probably ahve changed again and the worries you ahve now won't be there (even though others may have replaced them).
The economic situation in the country sucks at the moment and it is tough that you can't spend as much time with him as you would like... but I am sure that TJ still knows who is mummy is and loves you dearly. You probably never caught up on your rest post-birth before going back to work full time so I am sure you have cumulative fatigue. I am also sure that things will get better on this front and soon you will be able to cope again with looking after your little boy adn spending time with him at the weekends. IN the meantime, try looking at all the good points about your situation - you can be proud of yourself for providing for your little family, you now have more space to live in than you did when TJ was first born and I bet your DH has a lovely lovely relationship with him. Don;t be so hard on yourself xx
