Equi I would definitely leave the 3+ one with them. I'd tell then to give him it when he is 3. PIL always buy the wrong size clothing for DS and point out how nice and warm it is. Because obviously the boy has only just avoided freezing to death. And then they go and exchange it and we have to visit them again to be all grateful about the clothes again. Yes clothes are useful but I could do without the silly pantomime games.
I hate having useless tat bought for me. Last year we needed a new vacuum cleaner but DH said that his family wouldn't buy us one because they want to buy us presents
... But I was so pissed off with the vacuum cleaner not working I would have been as sad as it is really happy with a new one! Oh how life had changed
I asked DH to buy me a fancy nappy bag
for Christmas last year. I wanted it and I'm happy with it. 
Oh and the PIL will tell you to go and buy yourself something for Christmas. Then you give it to them with the receipt. They transfer you the money. Wrap the gift and put it under the tree. Then you go there open your gift and say lots of thank yous. It just seems really stupid to me. And sucks the fun out of opening presents.
And I'm slowly realising how much the PIL have been piling on the pressure and manipulating us all year
honestly DH and I are so stressed out about them. We can't just talk to them we have to play stupid games all the time because FIL is a control freak. I'm so angry and right now I just want to run far far away from them.
DH understands and isn't quite as dramatic as I am definitely not pregnancy related but I've said I'm not playing any more. I really think they have played a major part in making me miserable. 
Sorry this is so mememe.
