My baby is 1 month old, he keeps asking for milk in every 10 min after a feeding time of 15-20 min. He sleeps in ~5 min but I wake him up too to ensure he continue to drink. Sometimes he gets too hungry and crys loud that we give formula milk too but again after 20-30 min he'll be hungry. He wants to sleep with latching only. Is this normal? Please help to understand and give solution as it is very tiring for me.
