<human>: Good Day to you all! 
I wasn't sure where to post this but this seems to be the most relevant subreddit.

Long story short my boyfriend's son (turning 4) birthday is coming up. We have been together for a year but due to a mess of a divorce  He only gets to see him once a week. I have a good relationship with his son from all the times we've met so no issues there. 

So onto my dilemma. My boyfriend keeps a savings account for his son that he dumps money into every month.  I was thinking for his birthday I'll give him money (about 300~ish dollars) and help contribute to the funds,  but I don't know if that will come off as weird? Would a toy or something for his kid be a better idea?  Any perspective would be greatly appreciated.

Can you condense the text into three sentences or less?
<bot>: boyfriend's son's birthday is coming up and I want to give him around 300 dollars to add to his sons savings account. Will that come off as weird/is it an appropriate gift?
