help!! any advice?

Annabela
We are moving and we are temporarily staying with my MIL. LO used to go to daycare and when I would drop him off in the mornings no crying or anything. He would go to his teacher without a problem. Now that my MIL is watching him he cries most of the day. He screams and just has melt downs. He doesn't want anyone but me or my husband. I seriously thinks he just doesn't want to be with my MIL, because we spent the weekend at my cousin's house and there was none of this... any suggestions on what can help him? We still have about 3 weeks to go there and it breaks my heart seeing him like this every morning before I leave for work.
