Hey mama, totally normal yan sa 9 months, marami sa amin may ganyang phase, parang ang babies nila suddenly sleepy but restless pag gising kaya parang walang tigil hehe! Could be growth spurt, teething, or just their brain developing so fast na overloaded sila, kaya need ng mas maraming sleep pero ang body nila restless pa rin. Kung sobrang concerned ka or parang may fever or unusual signs, best to check with your pedia just to be sure, pero honestly most of the time it passes lang in a few weeks!
