She may only need two naps during the day at this age?? It will depend on the baby, Sebastian and chantelle had dropped down to just one day nap, between 30-60mins by that age.

Everything is a million times harder when you are suffering from sleep deprivation. I was happy chantelle would talk a bottle as well as breast, so I could express and DH could get up for at least one of the feeds back to sleep. We also started giving the first feed to bed of the night as a bottle of EMB because she would drink more from the bottle then the boob, and it made her have a longer sleep at that point. Of course this meant I was often up anyway, expressing whilst DH gave the bottle so that there would be another bottle ready to go, but she was settled easier and slept for longer - we ended up doing a combination of breastfeeding and formula later on, because I got sick of expressing; so don't make the mistake of thinking you are restricted to either breastfeeding OR bottlefeeding, it is possible to do both. Although I completely understand that you may not want to introduce the bottle at all.
