Muffin,
I do not have kid s myself but hope to have soon

but did baby sit and had my sister 2 kids
i think you got a lot of great advices here
maybe ask your peditrician ,give him a quick call
maybe something need to be change in the diet,
now yes get yourself a nice drink,and try to relax,i can imagine
it is not easy when you are by yourself,he he my huby was traveling
for work for years,so i know the feeling ,i didn t had a little one,but
other things!
Maybe an Aromatherapie Diffuser in your Tv room with Lavender
essential oil to relax you!
Where i grew up,they used to put Orange Flower water to calm you,so
you can put it in the baby bottle,of course ask the Peditrician first.
I m certain if the little angel see you feel more relax,she will eel as well.
Hugs.
do you like pet s ?
and if you have time to take care of one,i can tell you ,i was so glad to
have my Lab,i felt less lonely when hubby was away on work trip,
