What does your baby sleep in!

Kyara

My baby is 5 months ( we live in the UK ) and she sleeps in a 3.5 tog grow bag, a short sleeved vest and a all in one suit, however she still feels chilly on her face some times. Our house is normal, not cold. Some nights I have to put the bathroom window on the vent due to it being hot, I sleep with nothing on and a 13.5 duvet and in the night when I’m feeding her I get cold. What I am wondering is could my baby suffer with the cold more than others? She is waking a lot and I don’t understand why. Any ideas ? Thank you
