my LO is 18 months old and I brought her the tommee tippee sports insulated cup. she uses it as a pacifier I can say she just holds it in her mouth all day when she’s not playing. she falls to sleep with it as well. mind you she took herself off a regular pacifier at a few months and will not suck one so I guess she uses the cup instead. well last night her dad threw her cup away and I brought her one that doesn’t have any spout on it. it’s the 360 spill proof cup. she hates it. she screamed ALL NIGHT long for her other cup and he refused to give it to her.. is this okay? she’s drinking from the cup but she’s looking for that comfort from the other one. I get upset seeing her cry.. she’s been whining on and off all day and I think it’s because of the cup.
