I second buying/getting second hand gear. Try the local car boot I got a baby bath for a £1, a top and tail bowl x 2 for 50p each, a changing box for downstairs for £1. Breast pump electric Unused for £10. Avent electric steam sterilzer £4. Baby gym £2. Baby swing Graco £2. Few toys £1 each. I had 2 cotton jackets (neutral tags still on from Next) 50p each. If I knew the gender the amount of clothes is unbelievable. I have also had loads given to me clothes, toys, stroller, bumbo seat and tray, monitor, cot for the in laws, moses basket and stand, bouncing chairs x 2 I have saved loads.
Other tips if baby inconsolable try skin to skin (back to basics), if baby is snuffly at 3 months plus and you have a bump wedge from when pregnant put under matress to elevate head slightly. Good for colic too. That should do for now.
