How do you all feel about letting our LO?s have blankets in their cribs over night? Ben will be 9 months a week from today. I found out recently that my sister (who watches Ben during the day) puts a blanket on him while he naps. She didn?t want him cold as her house is a little on the chili side. She feels that he?s fine with it and I shouldn?t worry. (Even though I provided her with a sleep sack for her house!) I KNOW it?s a SIDS issue, but till what point? Ben is put to bed with a sleep sack currently, but I?m about to retire it because he?s too long for it. Soon it will be summer and I will have my air conditioning on at a cool 68! He does flip over on his tummy once we put him down. He?s pretty mobile when he?s awake, sitting up by himself, pulling himself to standing in and out of his crib, and walking while holding on to furniture for a couple of months now. Should I be okay with him having a blanket instead of his sleep sack now? Paranoid momma? Thoughts on this? I am going to ask Ben?s pediatrician on the 30th but I figure he?ll just give me the PC answer of it?s a sids risk till 1. I want to know what the real mom?s think.
