rewarding your kids🏅🎁🎉

LadyB💕
Okay so first of all I know "it's none of my business because I'm not his wife" that's what I've been told a lot here but I really want to be able to guide my SO with this kind of situation. He has 2 kids from previous relationship. 5 year old and 4 year old. The oldest just started going to school and is actually doing an amazing job! Has never gotten in trouble, listen to her teacher, does her school work and all! Which is amazing! The other day my SO saw hew she told him that she was doing good and that she wanted a gift because of the amazing work she was doing. Which yeah it's great I mean why not? But when I asked what she wanted he told me she said a tablet. I mean cool right? But I said didn't she have one already? And he said yes but that she said "her brother broke it" which by the way I know he has one too so I'm not sure why he would have "broken" hers. Also they already came with internet included so they could take them everywhere and not have to worry about that so he is still paying for that. My question to all of you is, is it too much of a gift? Or should he get it for her? 
Let me just add that right now he hasn't been working so he is a little tight on money. He is an amazing dad and always tries to do his best for his kids. And is always on a constantly fighting with the babies mom but that's a whole other story. I know as a parent is hard saying no to your kids and in this case probably even more but like I said I just really want to help my SO and give him some guidance. Thanks in advance ☺️
