Yes please.

Yes its hot now u can use fan but do nt keep babys ears open use cotton cap or money cap. Because ur baby is too small

The baby can take the same temperature as u . U can have the baby covered with cotton comforters as it's summer time.

If it is hot please switch on the fan just cover him with light cotton clothes..

Just cover ur baby's chest with a blanket or some cloth. Dont keep baby naked under the fan or in the ac.
