@atlanta Be gentle on yourself mama, you’re doing the hardest job in the world, the best way you know how!
I went through all of this with my little one (she is almost 4 months old now) I’ll try and give some tips best I can.
Eating - my girl gets super uncomfortable if she needs to burp, she also doesn’t like getting burped over the shoulder. I sit her on my knee with one hand on her chest and the other on her lower back, I straighten her back out and I usually get a nice burp. If your nursing, offer the other side when she is finished (burping in between)
Bathing - key is getting the water temp right, making sure the room is warm. Sometimes it helps to lay a cloth across their chest and keep putting warm water to it to keep their core warm. When I take my girl out of bath I let her latch on right away, it soothes her. Lately I started using the hair dryer on low and she looooooves it! Sometimes it even puts her to sleep! Also, I’ve had baths with her and it is the most special thing (make sure you have someone to pass you baby and help both of you out of tub)
Tummy time - tummy time does not have to be on the floor. Laying reclined with baby on your belly counts as tummy time, lay baby across your legs counts. Holding baby up with head supported also builds neck muscles. I bought the Fisher Price play mat and it was a GAME CHANGER!!!! My girl loves it. She will do tummy time on it or she loves to lay on her back on the nursing pillow playing with the toys that hang. But beware , those songs will be stuck in your head for a lifetime!
Lastly, I promise it does get better. How old is your LO?
