Hi Aleisha,
Not sleeping thru the night is really hard on you and him.
I know you wont want to hear this, but trust me, I have done this with 3. He is old enough that he doesnt need to eat thru the night. The nursing is his comfort to go back to sleep. He wakes up because that is the routine that he is in. At 4 months old they are able to soothe themselves to sleep at night. As hard as it is for you, letting him cry himself to sleep and NOT getting him when he wakes up in the middle of the night is the best way. It is not cruel to him. In the end it will be better for him, because he will get the sleep he needs and his mommy will too. I have a 9 month old as well, and she is pretty much on the same schedule as your little one. 2 naps a day around the same time, but she sleeps for 2 hours during those each naps, and I also put her to bed at 7:00pm. She sleeps all night until 8:00am the next morning. When she hit 4 months, I let her cry if she woke up at night. It took about 3 to 4 nights of HOURS of crying, but after that 4th night, she has never woken up again.Its because her routine changed and her body adjusted to not waking up.
Ive done this with all three of my babies and all three have slept thru the night at or before 4 months and still do.
I know with your first it is really hard to hear them cry. Instincts kick in and mommy mode starts and you want to run to them, because crying to moms is "somethings wrong".
But he will be ok. I have 2 best friends, one with 4 kids and the other with 3 kids. Both did not let their first born babies cry themselves to sleep and they were both well over a year and a half before they slept thru the night. With their next babies, they have let them cry themselves back to sleep and those babies slept thru the nights at around 4 months.
I feel for you so much, because i have been where you are. It WILL get better, I promise. There is light at the end of the tunnel! Just keep going. If you can try it for a few nights, your little guy will be sleeping thru the night in no time.
