Juanita - I know EXACTLY what you mean {hugs}...
It's like all of a sudden, I'm now the "bad" parent. Luckily my girl has an amazing bond with her daddy, so I get a lot of slack there being pregnant, taking naps etc. But like you say - one day all will be great and next moment is World War 3 in our house. Then it's jealousy overload!!!
Oooh, and she's a master now with manipulating hubby and me against each other! If the one doesn't want to give in on something, then she runs to the other parent... And we both put our foot down, she runs to Ouma & Oupa (who stays in a granny flat on the property)... So she's got her bread buttered ALL OVER!
Unfortunately I'm the strict parent, as she just turns daddy completely around her finger...
I have however decided - should I ever go and buy baby stuff again, I won't take her along

She makes me feel too guilty and then I end up buying for her instead of baby. So next time I will arrange a play date fro her and I can go shopping in peace and quiet, without being rushed and guilt-tripped.
Gosh I must sound like a terrible mom if I read through this now...But trust me: any mom with an older child, will be able to relate
