Childcare Needed

My baby is almost 5 months old , he usually takes naps during the day he has an 3 to 4 hour wake window inbetween naps sometimes he doesnt he does tummy time maybe once or twice a day watches ms Rachel nd I shower him at about 9:30 cover him well nd feed him 6-7 oz bottle so he can go to sleep he will probably wake up once or twice if it happens he will completely fall asleep at 2:00 a.m. . This will be the first time I will be far from him I dont know how he will respond other than that he is a really happy baby.
