Do you have a Daddy cd? His chaplain probably has books he can read on CD and send it to you. Then every night while she is in bed play it. This is her Daddy time. Put it on continuous loop.
Stop counting down. Say Daddy is in Iraq, or A, wherever, he will be home after Christmas, after Thanksgiving, etc. Do not reason with her, he is gone he will return, short and simple.
Are you near a base? Get involved in some mom and me kinds of activities with other moms.
Move her bed into your room.
Do not lament that Daddy is gone and be sad. THey go and come back and go and come back. It;s a vicious cycle. But the happier you are and the more self sufficient you can be for her and the baby the better.
Can your mom or MIL come for a visit?
Get into a routine, with the baby right now it's hard but pretty soon that one will sleep through the night.
Hire a teen to come in and be a mommy's helper. She can help you make dinner or you and baby SLEEP and she take the 2 year old to the park for an hour. This was the best thing I ever did.
We never skyped, it was too much. SO when he called I let them talk if they wanted and sometimes they didnt' want to. That was OK. I just let them be.
Do a care package every other week and she helps fill it. Or every month. We sent stuff every 7-10 days, even if just a card or picture drawn by the kids.
She will calm down. Her daddy is gone, you just had a baby, her world has been turned upside down. It takes time
Take walks and point out the birds and squirrels, the fresh air will help her be more tired and she will sleep better.
And do not lay all this on your hubby. He is already stressed that you are having a hard time with your little ones. Put on a brave face and cry to us and your mom or his mom or your girlfriends. I know it's hard.
Next January when he does get home your two year old may not want to have anything to do with him. It's OK, she will in time. My girls are 13 and 15 and they are Daddy's girls to the max. He has spent over half my 13 yo's life deployed.
YOu're going to get through this and you will look back on this year and say How did I ever!?!?
((((HUGS)))) M. and God Bless you and your hubby.
