Definitely very thoughtful of you! My Mum has a portacot, highchair and lots of toys for my DD to play with at her house. My MIL on the other hand has nothing! Every time we go to visit her we have to take a portacot and portable highchair with us and I dread it as it is a pain in the backside when it already feels like we have to pack so much without considering these things! Our DD is her 4th grandchild so I would have thought she would have the basics already.
DH + Me + DD (born 11/10/12) = our little family :-)
