Mommy hello? baby is 1 month old. Loves to sleep on her back, can lie down until you pick her up?? How many minutes is normal? I lift after 20-25 minutes, at the beginning 10-15 mins layed…. Last days she releases drool bubbles, I heard that it happens when teeth are cutting, but we're only 1 month ? Legs and hands constantly cold, I wear 2-3 socks, sometimes warm, sometimes cold anyway? In the evening I massage chicken Mayem, probably you will say why, but he warms…
