According to my MIL, my 4 month old son is spoilt.

He has a fair few toys because like most babies he gets bored quickly. When he moans or cries I cuddle him. How exactly is that spoilt??? Whenever the MIL comes over or we go to hers she always calls my boy naughty, calls him names like once she called him stupid because he sucks his fingers, called him Gollum then last night called him Dopey. I'm getting annoyed by it because when he starts understanding things he'll get a complex. My other half thinks I slag his family off if I say they're doing something I don't like with my boy. Can you really spoil a baby with cuddles??
