Harman, what kids want is love and affection and your time and that's exactly what you're giving. Children are not as bothered about the number of presents they get as you think. They can never be a substitute for your time. You gave her a lovely day out and she'll remember that.
When we were kids, my Mum and Dad were really struggling (when I was born my dad was still at uni, and also when my brother was born) - we were loved, cuddled, laughed with but we didn't get big flash presents - they had 3 of us and couldn't afford it. I only know that now but was oblivious as a child because I was loved and happy.
My cousins lived with their Mum and used to get the most amazing presents from their Dad at Xmas but who do you think they spend all their time with now as adults - yep, their mother, because they had everything they needed from her and it wasn't stereos and tvs for Xmas.
Don't you worry.
