If you are bottle feeding you can put her in a 4 hour routine as for this week. My daughter is 8 weeks too and is in a 4 hour easy. She eats 4 or 5 oz. of formula and if she wakes up early we play. I bath her at 6:30 and feed at 6:45 and then sleep. I increased each day 10 more minutes for the next fed. If she is supposed to eat at 11 I gave her at 11:10 the first day, the second at 11:20 and so on until finally she gets there, but you need to be sure to give her enough amount of formula for her to take it. How to know? If for a whole day she drinks 3 oz. and finish them completely (8 out of 10 bottles or 7 out of 10) that means you need to put another oz. of milk.Until she reaches completely. Hope it helps and works. If questions i will be pleased to help. Keep waking her up at the 3 hours or 3 10 or 3 20. Play a little if the 2 hours had passed. The decision of the 3 hour routine is up to you.
